Traveling with a pet takes more planning than most people expect. Airlines have strict size limits, documentation requirements, and breed restrictions. Hotels advertise as “pet-friendly” but tack on surprise fees and weight limits. International trips can require months of preparation. And your pet’s comfort matters just as much as the logistics.
This guide covers everything you need to travel confidently with your dog or cat. You will find current airline policies with fees compared side by side, road trip safety essentials, hotel booking tips, international travel requirements, ways to manage anxiety and motion sickness, and a complete packing list. Whether you are flying cross-country or driving to a cabin for the weekend, the goal is the same: a smooth trip for both you and your pet.
Before diving in, make sure your broader trip logistics are covered. Our complete trip planning guide walks through budgeting, booking, and organizing every detail of your travel itinerary.
Preparing Your Pet for Travel
Good preparation starts weeks before your departure date, not the night before. A little effort upfront prevents most of the problems travelers encounter with pets.
Visit Your Veterinarian
Schedule a vet appointment 2 to 4 weeks before your trip. Your veterinarian will confirm your pet is healthy enough for travel, update vaccinations, issue a health certificate if needed, and discuss options for anxiety or motion sickness. Many airlines and hotels require documentation that can only come from this visit, so do not skip it.
If you are flying, most airlines require a health certificate (also called a Certificate of Veterinary Inspection) issued within 10 days of travel. Some airlines extend this to 30 days. Ask your vet which form is needed for your specific airline and route.
Microchip and ID
Make sure your pet’s microchip information is current with your cell phone number and address. If your pet is not microchipped, now is the time. A collar with an ID tag is essential too, but tags can fall off. Microchips cannot. For international travel, an ISO-standard 15-digit microchip is required by most countries.
Carrier and Crate Training
If your pet has never spent time in a carrier or crate, the worst time to introduce it is your actual travel day.
- Start 3 to 4 weeks before travel. Leave the carrier open at home with treats inside. Let your pet explore it voluntarily.
- Gradually increase enclosed time. Close the door for a few minutes, then 15 minutes, then an hour. Reward calm behavior.
- Simulate the trip. Carry the loaded carrier around the house. Take short car rides with the pet in the carrier. Build positive associations before the real thing.
Use a trip planning checklist to track all your pet travel prep tasks alongside your own packing and booking deadlines.
Flying with Pets: Policies, Fees, and Requirements
Every airline has different rules for pet travel. Fees range from $100 to $150 per flight segment for in-cabin travel, and policies on carrier size, weight limits, and breed restrictions vary significantly. Here is what you need to know.
Documentation for Flying
- Health certificate: Required by most airlines, issued by your vet within 10 days of departure (some allow 30 days). Must confirm the pet is healthy and fit to fly.
- Rabies vaccination proof: Current rabies vaccination certificate showing the date administered.
- Pet reservation: Airlines limit the number of pets per flight, sometimes to just 2 to 4. Reserve your pet’s spot when you book your own ticket.
- For international flights: A USDA-endorsed health certificate, import permits, and destination-specific paperwork (covered in the international section below).
Airline Pet Policies Compared
The table below compares in-cabin pet policies for major U.S. airlines. Policies change, so always verify directly with the airline before booking.
| Airline | In-Cabin Fee | Cargo Option | Max Carrier Size (in-cabin) | Weight Limit | Notes |
|---|---|---|---|---|---|
| American Airlines | $150 per segment | Yes (AA Cargo) | 19 x 13 x 9 in | 20 lbs (pet + carrier) | Brachycephalic breeds restricted in cargo |
| Delta Air Lines | $150 per segment | Yes (Delta Cargo) | 18 x 11 x 11 in | Must fit under seat | Brachycephalic breeds restricted in cargo |
| United Airlines | $150 per segment | Yes (PetSafe) | 18 x 11 x 11 in | Must fit under seat | Brachycephalic breeds restricted in cargo |
| Southwest Airlines | $125 per segment | No | 18.5 x 8.5 x 13.5 in | Must fit under seat | In-cabin only, no cargo option at all |
| JetBlue | $125 per segment | No | 17 x 12.5 x 8.5 in | 20 lbs (pet + carrier) | In-cabin only, cats and dogs allowed |
| Alaska Airlines | $100 per segment | Yes | 17 x 11 x 7.5 in | Must fit under seat | Most affordable major airline for pets |
| Frontier Airlines | $99 per segment | No | 18 x 14 x 8 in | Must fit under seat | Cats and dogs only, in-cabin only |
| Spirit Airlines | $110 per segment | No | 18 x 14 x 9 in | Must fit under seat | Dogs, cats, small birds allowed in cabin |
Important: Fees are per flight segment, not round trip. A connecting itinerary with one layover counts as two segments, so the pet fee is charged twice. Budget $200 to $300 or more for a domestic round trip with connections.
Breeds with Flying Restrictions
Brachycephalic (flat-faced or snub-nosed) breeds face significant restrictions, especially for cargo travel. These breeds have shortened airways that make breathing more difficult, and the stress and pressure changes of flight increase the risk of respiratory distress.
Breeds commonly restricted from cargo include:
- Dogs: Bulldogs (English, French, American), Pugs, Boston Terriers, Boxers, Pekingese, Shih Tzus, Lhasa Apsos, Cavalier King Charles Spaniels, Mastiffs (some airlines), and Affenpinschers
- Cats: Persian, Himalayan, Burmese, and Exotic Shorthair
Most of these breeds can still fly in-cabin if they meet the size and weight requirements. The restrictions primarily apply to cargo hold travel. If you have a brachycephalic breed that is too large for the cabin, you may need to consider ground transportation or a pet shipping service that uses climate-controlled vehicles.
Cabin vs. Cargo: Which Is Right for Your Pet
Choose In-Cabin When:
- Your pet and carrier together weigh under 20 pounds (or fit under the seat on airlines without a strict weight limit)
- Your pet is calm in enclosed spaces and can stay quiet for the duration of the flight
- You want to monitor your pet throughout the journey
- Your pet is a brachycephalic breed
When Cargo Is the Only Option
- Your pet is too large for in-cabin travel (most dogs over 20 pounds)
- You are traveling with multiple pets and the airline limits in-cabin to one per passenger
- Your destination requires cargo arrangements (some international routes)
Making Cargo Travel Safer
- Book nonstop flights. Transfers add stress and handling risk.
- Avoid extreme weather. Do not fly cargo when temperatures exceed 85F or drop below 45F at either the departure or arrival airport.
- Choose early morning or late evening flights in summer to avoid peak heat.
- Use an airline-approved, hard-sided, IATA-compliant crate with “LIVE ANIMAL” labels, directional arrows, food and water dishes attached to the inside of the door, and absorbent bedding.
- Attach your contact information and a photo of your pet to the crate exterior, along with emergency vet contact information.
- Do not sedate your pet unless your vet specifically prescribes it for air travel. Sedation affects breathing and temperature regulation at altitude, which increases risk rather than reducing it.
Road Trips with Pets
Driving with your pet offers more flexibility than flying, especially for larger dogs. You control the schedule, stops, and environment. But car travel has safety requirements that many pet owners overlook.
Car Safety Essentials
- Restrain your pet. An unrestrained 60-pound dog becomes a 2,700-pound projectile in a 35 mph crash. Use a crash-tested harness attached to the seatbelt, a secured crate, or a pet barrier between the cargo area and the passenger cabin.
- Never let pets ride in the front seat. Airbags deploy with enough force to seriously injure or kill a pet.
- Never leave pets in a parked car. Car interiors can reach 120F within minutes on a warm day, even with windows cracked. This is illegal in many states and can be fatal.
- Keep cats in a carrier at all times. A loose cat can get under the brake pedal or cause a distraction that leads to an accident.
Planning Stops Along the Route
Stop every 2 to 3 hours for bathroom breaks, water, and stretching. Apps like BringFido and GoPetFriendly help you find pet-friendly rest stops, parks, and restaurants along your route. Always use a leash at rest stops, even if your dog has reliable recall. Unfamiliar environments are full of distractions, new smells, and escape opportunities.
If you are planning a longer road trip, our road trip guide covers route planning, packing, budgeting, and finding the best stops along the way. Pair it with pet-specific planning for a trip that works for everyone.
Preventing Motion Sickness
Dogs and cats can both get carsick, especially puppies and kittens whose inner ears are still developing. Signs include drooling, lip licking, yawning, whining, vomiting, and restlessness.
- Feed a light meal 3 to 4 hours before driving. Do not travel on an empty stomach or a very full one.
- Keep the car cool and well-ventilated. Crack a window slightly for fresh air flow.
- Face your pet forward. Position their crate or harness so they can see out the front windshield rather than the side windows. Side-window views create more motion sickness.
- Take frequent breaks. Short walks on solid ground help reset the inner ear.
- Ask your vet about medication. Cerenia (maropitant) is an FDA-approved anti-nausea medication for dogs that works well for car sickness. Your vet may also recommend meclizine for mild cases.
Pet-Friendly Hotels and Accommodations
“Pet-friendly” means different things at different hotels. At one property it means complimentary treats and a dog bed at check-in. At another it means a $150 nightly surcharge with a 25-pound weight limit and a list of restricted breeds. Always call ahead and confirm the actual policy.
What to Verify Before Booking
- Pet fee structure: Per night, per stay, or per pet? Fees range from $0 to $150 per night.
- Weight and size limits: Many hotels cap at 25 or 50 pounds.
- Breed restrictions: Some hotels ban specific breeds regardless of the individual dog’s size or temperament.
- Number of pets: Most limit you to 1 or 2 pets per room.
- Room restrictions: Some properties allow pets only on the first floor or in specific buildings.
- Damage deposit: Some hotels hold a refundable deposit of $50 to $250.
Hotel Chains with the Best Pet Policies
- Kimpton Hotels: No pet fees, no weight limits, no breed restrictions, no cap on the number of pets. The gold standard for pet-friendly travel.
- La Quinta by Wyndham: No pet fees at most locations. Two pets per room allowed.
- Red Roof Inn: One pet under 80 pounds stays free at most locations.
- Motel 6: One pet per room, typically free.
- Best Western: Pet-friendly at most locations. Fees and policies vary by property, usually $20 to $50 per night.
Vacation rentals on Airbnb and Vrbo often provide more space and fewer restrictions than hotels. Filter for “pet-friendly” listings and always confirm the pet policy directly with the host before booking. Some listings allow pets but charge a cleaning fee or restrict areas of the home.
Hotel Room Tips
- Bring a portable pet gate to block off areas you do not want your pet accessing.
- Place a familiar blanket on the floor or bed so your pet has a “home base” that smells normal.
- Do not leave your pet alone in the room unless you are confident they will not bark, scratch doors, or have accidents. Many hotels will charge for damages or complaints from other guests.
- Walk your pet before checking in so they arrive calm and have had a bathroom break.
International Pet Travel
International pet travel is significantly more complex than domestic. Some countries make it straightforward. Others require months of preparation, blood tests, and quarantine. Start planning 4 to 6 months before your trip.
Standard Requirements for Most Countries
- ISO microchip: A 15-digit ISO-standard microchip. It must be implanted before or at the same time as the rabies vaccination for the vaccination to be considered valid.
- Rabies vaccination: Current, with the administration date recorded on all health documents.
- USDA-endorsed health certificate: Your vet completes the health examination form, then it must be endorsed by a USDA APHIS Veterinary Services office. Allow 2 to 3 weeks for this process.
- Import permit: Required by some countries. Applications may need to be submitted weeks or months before arrival.
Countries with Strict Entry Requirements
- Australia: 10-day mandatory quarantine upon arrival. Pets must enter through approved routes only. The application process starts at least 6 months before travel, and only cats and dogs from approved countries are eligible.
- New Zealand: Similar to Australia. Minimum 10-day quarantine with extensive pre-travel testing and documentation.
- Japan: A 180-day quarantine period can be reduced to as little as 12 hours with proper advance preparation. This requires a rabies blood titer test performed at least 180 days before arrival, along with two rabies vaccinations and a microchip.
- United Kingdom: No quarantine if entering under the pet travel rules with a microchip, current rabies vaccination, and proper health documentation.
- Hawaii: Although it is a U.S. state, Hawaii has its own quarantine program. A 120-day pre-arrival process (requiring two rabies vaccinations, a blood titer test, and microchip verification) can reduce the 120-day quarantine to direct release at the airport.
EU Pet Travel
The European Union uses a standardized system for pet entry. Pets entering from the U.S. need a USDA-endorsed health certificate, current rabies vaccination, and an ISO microchip. Once you are inside the EU, your documentation works across all member states, making multi-country trips manageable with a single set of paperwork.
For more guidance on organizing complex international trips, our guide on how to plan a trip covers visa timelines, booking sequences, and document management that apply to both human and pet travelers.
Managing Pet Travel Anxiety and Stress
Travel anxiety is common in both dogs and cats. Signs include excessive panting, drooling, whining, trembling, refusal to eat, destructive behavior, and attempts to escape the carrier. Here is how to help your pet cope.
Weeks Before the Trip
- Carrier desensitization: Make the carrier a positive space. Feed meals inside it. Place treats and favorite toys inside. Leave it open in a common area of your home so it becomes familiar furniture, not a scary box.
- Practice trips: Take short car rides to positive destinations like the park or pet store. Gradually increase the duration over several weeks.
- Calming supplements: Products containing L-theanine, melatonin, or chamomile can reduce anxiety. Start them 2 to 3 days before travel so you can observe how your pet responds before the actual trip day.
- Pheromone products: Adaptil (for dogs) and Feliway (for cats) release synthetic calming pheromones. Available as sprays, collars, or diffusers. Spray the inside of the carrier 30 minutes before placing your pet inside.
During Travel
- Place a worn shirt or blanket with your scent in the carrier. Your smell is the most calming thing in your pet’s world.
- Cover the carrier with a light, breathable blanket to create a den-like environment. This is especially effective for cats.
- Speak calmly. Your pet reads your body language and tone. If you are stressed, they will be too.
- Offer small, high-value treats to create positive associations with the experience.
- For car travel, keep the temperature cool and consider playing soft classical music. Research has shown that classical music reduces cortisol levels in dogs.
When to Consult Your Veterinarian
If your pet has severe travel anxiety that does not respond to training, desensitization, and supplements, your vet may prescribe anti-anxiety medication specifically for travel days. Common prescriptions include trazodone and gabapentin for dogs, and gabapentin for cats. Never give your pet human medications or sedate them without veterinary guidance. Sedation at altitude can suppress breathing and cardiovascular function, creating more risk than it prevents.
Best Apps and Tools for Pet-Friendly Travel
Several apps make traveling with pets significantly easier by helping you find pet-friendly stops, accommodations, and services along your route.
- BringFido: The most comprehensive pet travel app. Search for pet-friendly hotels, restaurants, attractions, and outdoor activities in any city. Includes reviews from other pet owners and details on specific pet policies.
- GoPetFriendly: Excellent for road trip planning. Maps pet-friendly rest stops, parks, beaches, and accommodations along your driving route.
- Rover: Find pet sitters and dog walkers at your destination if you need a few hours away from your pet for activities that are not pet-friendly.
- Pet First Aid by American Red Cross: Step-by-step instructions for common pet emergencies. Works offline, which is important when you are in remote areas without cell service.
- AllTrails: Find dog-friendly hiking trails at your destination, filtered by difficulty, length, and whether dogs are allowed off-leash.

Traveling with Pets to National Parks
National parks are a popular destination for pet owners, but most parks have significant restrictions on where pets can go. In general, pets are allowed in campgrounds, on paved roads, and in parking areas, but they are not allowed on most trails, in wilderness areas, or inside park buildings.
Some parks are more accommodating than others. Yellowstone, for example, allows leashed pets on roads, parking areas, campgrounds, and a few specific trails. If you are planning a trip to Yellowstone, our Yellowstone trip planning guide covers logistics, the best times to visit, and how to structure your days in the park.
Before visiting any national park with a pet:
- Check the park’s specific pet policy on nps.gov. Rules vary significantly between parks.
- Pets must be on a leash no longer than 6 feet at all times in every national park.
- Never leave your pet unattended in a vehicle, especially in warmer months.
- Be aware of wildlife. An unleashed or poorly controlled dog near elk, bison, or bears creates a dangerous situation for everyone.
- Consider using Rover or a local pet sitting service for days when you want to hike trails that do not allow pets.
Frequently Asked Questions
How much does it cost to fly with a pet?
In-cabin pet fees on major U.S. airlines range from $99 to $150 per flight segment. Alaska Airlines and Frontier charge $99 to $100, while American, Delta, and United charge $150 per segment. Cargo transport through airline programs costs $200 to $1,000 or more depending on the pet’s size, distance, and crate dimensions. International flights typically charge higher fees: $200 to $500 for in-cabin and $500 to $2,000 or more for cargo. Remember that fees are charged per segment, so a round trip with one connection in each direction means four segments.
Can cats fly in the cabin on a plane?
Yes. Most major airlines allow cats in the cabin in an approved carrier that fits under the seat in front of you. Cats must stay in their carrier for the entire flight. The same size and weight limits that apply to dogs apply to cats, typically a combined weight of 20 pounds (pet plus carrier) and carrier dimensions around 17 x 11 x 8 inches. Cats generally handle flights well because they naturally prefer enclosed, den-like spaces.
What documents do I need to fly with a pet?
For domestic flights within the U.S., most airlines require a health certificate issued by your veterinarian within 10 days of travel and proof of current rabies vaccination. Some airlines accept health certificates issued up to 30 days before travel. For international travel, you need a USDA-endorsed international health certificate, proof of all required vaccinations, microchip documentation, and potentially an import permit from the destination country. Requirements vary widely by country, so start the process at least 3 to 4 months in advance.
How do I calm my dog on a plane?
Start with a familiar blanket or a shirt with your scent in the carrier. Exercise your dog thoroughly before heading to the airport. Consider a calming supplement containing L-theanine or melatonin (consult your vet first), a ThunderShirt or anxiety wrap, or a calming pheromone spray like Adaptil. Avoid sedatives unless specifically prescribed by your veterinarian, because sedation can cause respiratory and cardiovascular problems at altitude. The most effective strategy is practicing carrier time at home for several weeks before the flight so the carrier feels safe rather than stressful.
Is it safe to put a dog in cargo on a plane?
Cargo travel is generally safe for healthy, non-brachycephalic dogs when handled by reputable airlines with pressurized, temperature-controlled cargo holds. However, risks increase significantly for flat-faced breeds like Bulldogs, Pugs, and Boston Terriers, which already have compromised airways. Many airlines ban these breeds from cargo entirely. Extreme temperatures also increase risk, and airlines impose temperature embargoes when conditions are too hot or too cold. If your pet qualifies for in-cabin travel, it is always the lower-risk option.
Do I need a pet passport for international travel?
The term “pet passport” is used formally in the European Union. For U.S. travelers entering the EU, you do not get a pet passport but instead use a USDA-endorsed health certificate along with proof of rabies vaccination and microchip documentation. Once inside the EU, these documents function similarly to a passport, allowing your pet to travel between member states. Other countries use their own systems, typically requiring specific health certificates and import permits. Check your destination country’s requirements at least 4 to 6 months before travel.
