I believe that you are not allowed to have any liquid on your hand bag,but food I think it is ok.I go to Brasil evry year and I bring a lot of protein bars,nuts,and fruit (but fruit only in the airport,not in the plain,at least I’ve never taken a fruit inside of the plain.)
Maybe the international flights rules are different.
I just want to bring some raw crackers. I have a 2 hour layover in L.A. and just want to stay in the airport. Thus wanting food with me. Thanks for your help. I guess Ill see how it goes when I bring some raw crackers in a baggy!
