I have used the dual jetway at AUS
several times; I think it is mostly used for DAL
flights. I have only de-planed from it, I have never boarded with it (I don't even know if they use it for boarding). I enjoyed the convenience of it, because one of my pet peeves is airline passengers to take forever to get off the plane. However, if what KAUS said is true, WN
might want to reconsider it.
I think the wide-body dual jetway concept, which is much different from the bridge at AUS
, is probably more useful. Boarding a 777 through a single jetway is a nightmare sometimes, I can't imagine boarding a 747 or A380 through a single gate (does anyone know ... will all
A380 gates have dual jetways?)
