how much is a carry on bag on frontier?
<answer> 35 pounds <context> Upon booking your Frontier flight, get out your measuring tape to ensure your bag is the appropriate size. When you fly with Frontier Airlines, you're allowed to board the plane with one carry-on bag. The bag must weigh no more than 35 pounds and its maximum external size cannot exceed 10 by 16 by 24 inches. If the piece of luggage you wish to use as your carry-on bag does not meet Frontier's guidelines, you must pay to check the bag.
