Trabbi,
Since your brought it up again, I am trying to see why boarding using buses can be quicker. Buses at my airport are always available but my observations shows there is a long wait for the bus to fill and then driving off to the aircraft.
At the same time boarding via a jet bridge, pax can move rather swiftly and even late pax would not delay flight as much.
I am curious to see what can be done to shorten the delay. I suspect a lot of things are not visible to SLF so I am curious what are they. Also in my case the ground crew told me about a 20' delay which turned to be and remain 40'. Did the ground crew "shorten" the delay to make it look better?
If the last remarks are offending for the ground crew please disregard it!
