If a decent meal was $5-10 (maybe $15-20 in FC) on a long flight, I would certainly consider it. Would really depend on what you would get. Are we talking about a sandwich and chips? I can buy that in the airport and save myself a few bucks over what the airlines are likely to charge. I have to imagine that most leisure travelers, the folks who only fly a few times a year yet represent the bulk of passengers on any given flight, would bring their own food.
