Subject: Carry ons
I know that United Airlines had those templates placed in the San Francisco Airport, but they were sued by other airlines that were not so strict. The suit claimed unfair competition and discrimination of other airlines requirements. The other airlines won the suit and United was suppose to have the templates removed.

Each airline does have a different requirement for the measurement of the carry ons, since they use different equipment. Some have larger luggage bins than others. If anything they should ban some of the strange things that people insist on shoving in those bins.
