London layover mini-itinerary builder for Heathrow, Gatwick, and London airport stopovers
A London layover can feel generous on paper and surprisingly tight once immigration, luggage, airport access, and return timing start taking minutes off the clock. Use this planner to work out whether you should stay airport-side, do one compact London outing, or treat the stop as a short city stay based on airport, layover length, luggage, and how confident you want the day to feel.
Built for the layover window where every airport decision changes how much London you can realistically enjoy.
The planner explains why your layover looks airport-side, compact, flexible, or city-stay worthy instead of giving a black-box answer.
Balances transfer time, luggage friction, first-time uncertainty, and the return buffer that matters most later in the day.
Work out what is actually worth doing during your layover
Answer a few practical questions and the planner will show the cleanest level of London ambition for your stop, plus why that recommendation fits.
Built for realistic planning, not fantasy layover itineraries that look good until the return journey starts to feel risky.
