Taking flight any suggestions?

I have to go on a business trip. This will be my first flight since having the band put in. Should I expect any problems? Any suggestions as far as taking protien along on the trip ?? I don't want to take a whole big container I'll only be gone four days. Protien as carry on or just in baggage?

My band is as tight as I can get it and still eat. I asked for the extreme before I moved and boy did I get it. My husband has finally figured out how much I can eat without throwing up. I was vomiting after every meal for awhile and live to far to go to the doctor every time I may need an adjustment. I'm concerned about eating in front of people because of eating slow and not being able to eat a full plate of food they serve. I've requested smaller portions and no large vegatables. I'd rather not eat than have to keep leaving the table to go vomit.

Anyone got anything else I'm forgetting about?
