regionaltard said:Not necessarily true. There are incremental costs associated with each passenger an airline handles. Your example is probably valid because the costs incurred to handle an additional ten passengers would probably be less than $550, but if the choice were between 50 pax at $200 a pop and 100 at $100 it would be far better to take fewer people willing to pay top dollar.
Airlines staff for the maximum capcity of the plane, if 1 person shows up or 300 show up you are going to have the same # of crew (defined by the FAA), ground crew, mechanics, gate agents, etc. More flights add huge incremental costs to an airlines, bigger planes/less flights make the $$$'s work much better.
I will address some of the other points brought up when I get a free moment. Nice to have a thread on the Majors Forum no less that debates some intersting points about the industry.
