Heathrow — Can you leave the airport?
A layover in London can be the best part of your trip — or a stressful dash back to the gate. Heathrow sits about 35 minutes from Paddington / Bond Street by airport rail, and there’s no sterile transit here, so plan for the border either way. Below we work out exactly how much layover time you need to leave, what a realistic plan looks like, and the visa and re-screening details that decide it.
