Gatwick travellers walk 1.2 miles to board flights
I know it always seems like there are some long walks at LGW...did not think it was quite that far!! Moving between CDG terminals seems much farther IME!
The study, carried out by Direct Line travel insurance, compares the distance that passengers must travel at some of Britain's busiest airports. It showed that travellers at Gatwick face the longest walk, using the distance from the terminal entrance to the furthest departure gate.
