Could anyone give a guideline for how much these things cost to build / use each time?
Relative to alternatives -
Stairs presumably almost zero for the airport / I heard MOL say $250k for both ends on a 737-800.
Mobile boarding lounges - only used in very small # of places (IAD to access concourses, JED, DFW???)?
FR's stunted piers at STN?
Does presence of any disabled pax make any difference - how quickly is the decision made or otherwise -
afaik baby use them at BHX, but if flight is late, they just use the steps.
Presumably certain a/c are too small to use them - iirc, Flybe do for the 146 if available, but not the Q400? At BHX, they seem to prefer busing pax to remote stands
