I also read this author's post about bankrupt airlines. I've always been aware of the subcontracted airlines (often I'd see two flight numbers rotating on the same screen or somewhere it would say X operated by Y) but I never stopped to think if I should check if one of those is actually bankrupt.

I don't fly within the US just because fuck the TSA (I'll take a train to Canada if I need to fly internationally), but I'm going to be more careful now about checking the subcontracted airline to make sure they're not in bankruptcy.
