Baggage policies vary dramatically between airlines, and fees add up fast if you are not prepared. Most US carriers charge $30 to $40 for the first checked bag and $40 to $50 for the second on domestic flights. Southwest Airlines remains the exception, including two free checked bags with every ticket. International flights on most carriers include at least one free checked bag in economy.
Carry-on rules are relatively consistent. Most airlines allow one carry-on bag (fitting in the overhead bin) and one personal item (fitting under the seat). The catch is basic economy fares on United, American, and Delta, which restrict overhead bin access. On these tickets, you can only bring a personal item unless you pay to upgrade or hold airline status.
Oversized and special items like sports equipment, musical instruments, and car seats have their own rules. Most airlines charge between $75 and $200 each way for items like golf clubs, skis, or surfboards. Strollers and car seats for children typically fly free. Always confirm special item policies before you arrive at the airport.
To minimize baggage costs, pack light and use a carry-on when possible. Airline credit cards often include free checked bags as a perk. And if you are booking through our agents, we will clarify the exact baggage allowance for your fare class and airline before you commit to a ticket.
