Checked Luggage Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14.

In 2026, the standard weight limit for a checked bag on most major international and domestic airlines is 50 pounds (23 kg) for Economy class. For passengers traveling in Premium Economy, Business, or First Class, this limit is often increased to 70 pounds (32 kg). Additionally, "Elite" status members of frequent flyer programs often receive the 70-pound allowance regardless of their cabin. It is important to note that most airlines will not accept any single bag that weighs more than 70 pounds for safety reasons (to protect baggage handlers), even if you are willing to pay an "overweight" fee. Bags exceeding this absolute limit are usually required to be shipped via a separate cargo service. For low-cost carriers like Spirit or Ryanair in 2026, the included weight may be even lower (often 40 lbs or 15 kg), and they charge significant fees for every pound over the limit. Always check your specific "Fare Rules" before heading to the airport.
