End of an era: Southwest Airlines no longer checks bags for free

Passengers checking bags on Southwest Airlines must now do what passengers on other airlines do:
pay for their checked bags.
The carrier’s longstanding and much-loved “two bags fly free” policy ended May 28, 2025.
Now Southwest Airlines passengers who don’t have a Southwest credit card, elite status or a certain class of ticket must pay $35 for the first check bag and $45 for the second.
Checked baggage fees on domestic US airlines

For many travelers, Southwest’s “two bags fly free” policy was the clincher when choosing which airline to fly.
But now those travelers may be looking around for other carriers and trying to figure out the checked bag fees.
So let’s take a look at what current checked bag fees are on most domestic U.S. airlines. Weight and size restrictions apply and are often not the same from airline to airline, so be sure to check.
In many cases, a credit card, cabin class or airline status will allow you to avoid these checked bag fees. And there may be discounts for prepaying your bag fees.
Here are some of the basic baggage fees as of May 28, 2025.
Alaska Airlines: $35 for 1st bag; $45 for the second bag.
American Airlines: $40 for the 1st bag ($35 if you pay online); $45 for the second bag.
Delta Air Lines: $35 for the 1st bag; and $45 for the second bag.
Frontier Airlines: Pricing for carry-on and checked bags varies by where (i.e. online or at the airport) and when you pay for it. And even by route. It can be confusing. And costly. Be sure to measure and weigh your bags and check the site for options.
