CHARLOTTE, N.C. —

A major airline at Charlotte Douglas Airport will be getting stricter about the size of passengers’ carry-on bags.

United Airlines is using new "bag-sizers" to make sure the bags aren't too big for the overhead compartment or under the seat in front of travelers.

The company said there's no change in the size limit -- just a better measurement.

Bags that are too big will have to be checked for $25.
