What to Do During Your Layover
Short Layovers (2-4 Hours)
With limited time, stay near the airport or focus on one quick activity:

- Shower & refresh – Many airports have shower facilities; check your airline’s website
- Grab a meal – Eat at the airport food court, but note prices are 2-3x higher than the city
- Walk around the terminal – Browse duty-free shops and explore airport amenities
Medium Layovers (4-8 Hours)
You have time to venture into London. Consider these highlights:
- Big Ben & Houses of Parliament – Iconic Gothic architecture; free to view from outside, tours available
