If your carry-on bag is too big, airlines typically have a few options: they may require you to check the bag at the gate, sometimes for a fee. To avoid this, measure your bag and compare it with the airline’s size restrictions before flying. If it's slightly oversized, consider repacking into a smaller bag or removing some items to fit in a sizer at the airport. Being proactive can save you time, money, and stress.
