I wouldn't be surprised if responsive/web-OK site views were budgeted away in favor of app development. They should be complementary, but this is an airline we're talking about.
Right, and the stupidity is twofold: that external access to resources (site/app) is a zero-sum game where x developers must be allocated to one or another goal without any coherence between them, which is source of the schism between app and mobileweb UXes, and that apparently nobody has spoken up to say that both products suck.
