But just because you have the right airline card doesn’t mean you’ll always get the checked-bag freebie, thanks to a plethora of gotcha exceptions found in the fine print of cardholder agreements.
For example, two major airlines — United Airlines and JetBlue Airways — require you to book airfare with their co-branded airline cards to be eligible for free checked bags on that flight. And sometimes the travel booking website you used might disqualify you from checking a bag for free.
Airlines made more than $7 billion from bag fees in 2024, according to the U.S. Department of Transportation, so maybe it’s not surprising that they limit their baggage-fee waivers.
Most of the time you’ll get the free baggage benefit without hassle and when you expect it. But it’s important to know about exceptions.
“You don’t want to use the wrong credit card, and spend a lot of money on your airfare, only to find out that doing so makes you ineligible for that benefit from your credit card,” says Henry Harteveldt, president of Atmosphere Research Group, a market research and advisory firm serving the global travel industry.

How bag-fee waivers work with many airlines
Usually, using a credit card’s checked-bag fee waiver is pretty easy. You simply won’t be charged if your card account is in good standing. How many fellow travelers on your reservation also get a free checked bag depends on your card. It may range from no additional passengers getting the benefit to eight others.
At the airport, whether tagging your own bags at a kiosk or using an agent at a ticket counter, if you follow the rules, you won’t be charged for a standard first checked bag and usually don’t need to have the card with you.
But, of course, rules for airlines differ, and most have a lengthy list of exceptions.
🤓 Nerdy Tip
The bag-fee waiver benefit of a co-branded airline credit card typically applies to domestic flights. Most international flights allow a checked bag for no extra charge. (Flights to Canada or the Caribbean may be exceptions.) The card often does not entitle you to an additional free checked bag.
10 gotchas for free checked bags
Checking your cardholder agreement is the best way to uncover details about the checked-bag fee waiver, but here are examples of exceptions from U.S carriers that you might find in the fine print.
Using the wrong credit card for airfare. Maybe the most notable exception involves airlines such as United, JetBlue and Alaska Airlines, which require you to pay for the airfare with their co-branded credit card to qualify for the fee waiver. If you’re flying on a “free” award ticket you paid for with miles on United, you must pay the taxes and fees with a MileagePlus card.
Booking on ineligible websites. United specifically says “unpublished fares, such as those purchased on priceline.com and Hotwire, are not eligible.” Alaska Airlines states that reservations made through third parties, including travel agencies and wholesale clubs, may not be eligible for the free checked bag benefit.
Excluding a frequent flyer number. With many airlines, the key to getting free checked bags is linking your frequent flyer number to your reservation. So you need to have a frequent flyer account and number and include it on every booking when you want to use the bag benefit.
Bringing big bags. The bag benefit usually doesn’t apply to overweight or oversized bags.
Adding extra bags. Typically, the benefit is for the first standard checked bag per person. Some cards may allow two bags each, including upper-tier United cards.
Elite status stacking. Frequent flyer elite status usually gets you a free checked bag, too. But typically you can’t “stack” the benefits of elite status and cardholder status to get two checked bags. Delta is a notable exception. Flyers with its lowest elite level, Silver Medallion, can get an extra bag free if they have a co-branded credit card with a checked-bag benefit. Higher elite levels on Delta already get more than one checked bag free.
Flying airline partners. While your bag benefit is good on regional carriers the airline uses as subcontractors — typically between small airports and hubs — it often doesn’t apply to codeshare flights. Codeshares are when two or more airlines sell seats on the same flight. The baggage policy of the airline operating the flight typically applies.
Being only an authorized user. Typically, the primary cardholder must be on the travel itinerary to get the baggage-fee waiver. Being an authorized user is not good enough unless you’re traveling with the primary cardholder on the same reservation.
Being a new cardholder. Some airlines warn that your credit card account must be open so many days before travel to get the benefit. JetBlue requires your card be open for seven days, while Southwest requires up to 14 days for the benefit to become available. Meanwhile, Delta says it’s available after you receive your physical card.
Other ways to get free checked bags
If you’re caught in one of the airline card exceptions and don’t have frequent flyer elite status, you can avoid shelling out cash for checked bags if you have other travel cards that might cover the expense.
Some luxury travel cards come with an annual travel credit that can be used toward checked-bag fees. And some general travel cards allow you to essentially erase travel expenditures like checked-bag fees by applying accumulated points to get a statement credit.
Also, some airlines waive bag fees for active military.
Rules about free checked bags vary by airline and can change over time. A quick online search should turn up the right page with an airline’s baggage rules and its co-branded card rules. Here are links to policies for some U.S. airlines:
While the airline card checked-bag fee waiver is valuable and generally easy to use, it doesn’t apply in all situations. So it’s worth a few minutes to examine the limitations of your bag benefit.
