New Jersey's senior senator is criticizing new recommendations aimed at reducing the size of airline travelers' carry-on bags.

Sen. Bob Menendez spoke Monday at Newark Liberty Airport to demonstrate how reducing the size of carry-on bags could increase costs for travelers.

The International Air Transport Association has proposed requiring the bags to be a maximum uniform size - 21.5 inches high, 13.5 inches wide and 7.5 inches deep. Menendez says that's about 20 percent smaller than what most airlines allow now.

Menendez says the new rule would force many travelers to pay for checked baggage. He plans to ask the airlines to reject the recommendation or, if they accept it, to reduce baggage fees.

New York Sen. Chuck Schumer criticized the new recommendations last week.
