This might be a silly question, but I wanted to ask before our trip.
Would a soft-sided cooler bag like this be allowed as a carry-on? I know the general guideline is 12 x 12 x 12 inches, but I am not sure how strictly that is enforced for soft bags that might be slightly flexible.
Has anyone used a similar cooler bag onboard before and had any issues at boarding or security?
Just trying to avoid any surprises at the port.
