for the DO, i flew JFK-IAH at 1:05 or 1:15 PM or something like that and got bupkus (spelling?). luckily, i brought my own victuals with me.
(though i do have to admit that i was surprised, given that continental supposedly serves "meals at mealtime." i can't imagine roughly 1 PM not being mealtime, especially at the hour one has to leave to get to the airport and especially the length of the flight.)
