Airline Carry-on Size Suggestions Could Mean You Need New Luggage

Airlines are fretting over how to fix a problem they created.
Since checked baggage fees have become common among U.S. carriers, the battle over overhead bin space in airplane cabins has become intense. Every boarding announcement is accompanied by a crowd of eager travelers, desperate to get their bags in the spaces above their heads.
On Tuesday, the International Air Transport Association (IATA) announced a new initiative "to optimize the accommodation of carry-on bags given differing carry-on bag sizes and airline policies."
According to IATA, The new suggested carry-on size, at 21.5 x 13.5 x 7.5 inches, "means that theoretically everyone should have a chance to store their carry-on bags on board aircraft of 120 seats or larger."
Current carry-on baggage allowances average 22 x 14 x 9 inches.
