TSA cannot reject a bag if it fits in the x-ray. I remember the dark days when Continental tried to put sizers up right on the front of the x-ray machines at security at Dulles. We just lifted it up and put our bags through as usual.

Continental wanted United, a unit of UAL Corp. , to remove the sizers at shared security-screening checkpoints at Dulles, claiming the templates were preventing its passengers from carrying their bags on board and thus hampering its business.

Continental said it has spent millions of dollars to retrofit its aircraft with larger overhead bins to accommodate travelers. "Baggage sizers are an example of a big airline's effort to 'herd' passengers through a cattle chute because they can't effectively respond to customers as individuals," Gordon Bethune, Continental's chairman and chief executive, said in a statement.
