how big can a carry on bag
However, make sure your carry-on bag is of a size permitted by your airline. Dimensions vary from airline to airline. These two legacy carriers allow each passenger one carry-on bag, and one personal item. In both cases, the carry-on bag must be no larger than 22 inches long, 14 inches wide and 9 inches high. US Airways also stipulates a maximum weight of 40 lbs. Delta says the carry-on bag must fit easily into its carry-on baggage gauges, located close to airport check-in desks. The gauges' dimensions are those of the largest permitted carry-on bag. Personal items allowed in addition to a carry-on bag include a briefcase, purse, laptop bag, camera bag or diaper bag.
