If you're someone who doesn't typically pack light, you may be searching for airlines with free bags, regardless if you want to check or carry on your luggage. In that case, there's only one domestic airline with free checked bags across all cabins and regardless of your elite status level: Southwest Airlines.

While most major "Legacy" carriers in the U.S. (like Delta, American, and United) and almost all "Budget" airlines (like Spirit or Ryanair) now charge for checked bags on domestic or "Basic Economy" tickets, there are several notable exceptions in 2026. Southwest Airlines remains the industry leader with its "2 Bags Fly Free" policy on every single fare, including their cheapest "Wanna Get Away" tickets. Internationally, most full-service Middle Eastern and Asian carriers—such as Emirates, Qatar Airways, and Singapore Airlines—still include at least one checked bag (often up to 25kg–30kg) in their standard economy fares. Furthermore, many major airlines continue to offer a free checked bag on long-haul international flights (e.g., New York to London) even if they charge for the same bag on a domestic leg. To avoid these fees in 2026, travelers frequently use co-branded airline credit cards or maintain "Elite" status, both of which typically grant a complimentary checked bag even on the most restrictive domestic tickets.
