Anyone been on an airplane or been rejected to board an airplane with a cast?
NO! Of course not! Unless you are hiding guns in it! lol just kidding! They will use a sensor to check it better, but you WILL be able to get on a plane with a cast! I have broken my arm about five times and my leg twice, so I know from experience that you shouldn't have any trouble as long as you don't put anything in it!
Dang girl! 5 times arm and twice leg. I guess you fly within the USA?
