Generally, yes, but you need to inform the ticket taker. You ll prob have to make a verbal promise to put it fully under the seat. Although for Dolby movies (there there is no under seats) that won't be an option; they ll prob give you an option to stow it under one of the tables in the lobby area, but at your own risk.
Yes
Yeah im sure you can but where are you going to store during the movie
