Carry on != personal item. Carry on max: 22 cm x 35 cm x 56 cm Personal item max: 22 cm x 25 cm x 43 cm On at least U.S. airlines the personal item is always free. The carry on isn't always free, e.g. Frontier. And also gate checking the 1st bag isn't always free, it can be quite a bit more expensive, again e.g. Frontier which will charge $60 at the gate.
