Do wheels and handles count?

Yes. Airlines measure the outside of the bag, wheels, handles and pockets included, and many suitcases sold by their packing-space size are bigger once you add the wheels. Measure yours before you fly.

What if my bag is only slightly too big?

Soft bags can sometimes squeeze into a sizer, but don't count on it: at Aeroméxico it's 0.3 in too long, Volaris it's 0.3 in too long and Viva it's 0.3 in too long. If the gate agent says no, checking it at the gate usually costs more than adding a bag when you book.
