Are you allowed to take your own food on the plane in the USA?
When the airline doesn't give me free food, I'll often just pack my own. It's usually nicer than what they'd give me anyway. I'd rather a nice homemade bacon and egg sandwich than the shit they serve you on a plane.
Departing from New Zealand I've never had an issue bringing my own meal. Obviously I can't bring something to drink, but I can buy something after security.
The one that annoys me more than food is charging for luggage. Especially since some airlines will add a luggage fee for every leg of the trip, which can add up to be very expensive.
