Updated: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.
