Flying Soon? Know the Carry-On and Personal Item Size Limits First

If you’re planning to fly anytime soon, it pays to know exactly how much you can bring aboard without running into trouble at the gate. A new roundup details the carry-on and personal item size restrictions for 33 major airlines, covering both U.S. and international carriers. While most airlines set a maximum carry-on size of around 22 x 14 x 9 inches, many—especially outside the U.S.—also enforce weight limits that can catch travelers off guard. Personal items must generally fit under the seat in front of you, though specific dimensions vary. With airlines increasingly charging for carry-ons in basic economy fares, understanding these rules is more important than ever to avoid surprise fees and travel headaches.
