Has anyone carried on snacks for the kids? I want to have stuff for the room that I know my kids will like, and also want to have it for the plane. Will they give me problems if its all packaged? I have goldfish crackers, cookies etc... I would prefer to put it in zip-lock bags to save space.
If we weren't flying stupid Air-Tran, I would probably take another suitcase, but they charge for them now

. I figured that I'd also carry on the kids clothes & our shoes. Has anyone encountered difficulty with any of the above?
