Airline Baggage Fees

The airline baggage fees listed here apply to passengers in the lowest fare class on flights within the continental U.S. They are often waived or reduced for passengers in higher fare classes, frequent flyers who have reached a certain status in an airline's loyalty program, customers who book with an airline-affiliated credit card, and active-duty military. Passengers with round-trip tickets must pay each way. Exceptions are generally made for strollers and child seats, mobility aids, and service animals. Unless otherwise specified, the standard maximum size for a carry-on bag is 22 x 14 x 9 inches. Oversize checked bags are measured in linear inches (length + width + height). Additional airline baggage fees may apply to sporting equipment and other specialized items.
