Question: are gym bags allowed as carry on?
Answer: Can You Use a Duffle Bag as a Carry On? Yes. As long as your duffle bag is within the airlines size requirements for carry on luggage, you can use a duffle bag as a carry on item. For most airlines and flights, that means choosing a duffle bag that is no larger than 9 inches x 14 inches x 22 inches (for most flights).
