Anyone know how long you should allow to get from Terminal 1 to Terminal 5 in Heathrow?
I know there's trains every 15 minutes that take 3 minutes to travel between one and the other, but looking at booking flights which leave just over an hour between arrival time and departure time. Never had a problem with this changeover time before, but with the different terminal, am I pushing it?
Have booked a bag into luggage, but can change that if needs be.
