The rule of 45, the airlines called it. When flying, you needed to add up all the dimensions of your carry-on suitcase -- length, width and thickness -- and if they came to more than 45 inches, you needed to check the bag.

The first passengers who push their way aboard airliners today get to stuff their fat bags into overhead bins, eating up space rightfully due meeker travelers who follow the rules and stay in line.

Question: Do you think airlines should crack down on passengers with over-sized carry-ons?
