North or South
"BA friends have always labelled Sarf Terminal as Charter and Low Cost Land, Chav city on occasions................being moved to there is going to hurt egos".
Historically that was true, sadly the North Terminal airside has gone downhill, whereas the South Terminal has massively improved both Landside and Airside.
As a passenger who uses the train to reach LGW, South wins hands down.
At least there will be an end to easy flights deplaning at the 'wrong terminal' with the passengers being bussed back to the correct terminal with all the discomfort and extra delay, this has happened to me a number of times and seriously Pxxxxd me off.
We have had charter flights at the North terminal for enough years that the 'executive club' image has long been dispelled since the days when it was prevalent in the early 1990s.
