I detest bus gates. I hate them at LAX, LHR, DOH, AUH, and everywhere else in the world I've had them. They scramble the usual order for planing/deplaning. You could be first in line to board at the gate, and end up crammed in the back of some nasty sick-making bus jostling across the tarmac, and last to get out and climb the stairs to the plane. You could be sitting right by the exit door, and end up last to enter the madhouse of immigration. I'm don't mind walking across the tarmac to or from the plane (as in the old SNA airport, or the now-closed SAN commuter terminal, or the BA gates in DUB), but no busses, please!
