On American Airlines in 2026, passengers in Domestic First Class and International Business Class are generally entitled to two free checked bags. Each bag can weigh up to 70 lbs (32 kg), which is a significant upgrade from the 50 lb limit in the Main Cabin. If you are flying in Flagship® First on select long-haul international or transcontinental routes, your allowance increases to three free checked bags, also at 70 lbs each. If you hold elite status, such as AAdvantage Executive Platinum® or oneworld® Emerald, you may be entitled to an additional bag or higher weight limits regardless of your cabin. Always check your specific itinerary in the American Airlines app, as certain "seasonal limitations" or specific destinations (like Cuba or Haiti) may have stricter caps on the number of bags allowed, even for premium passengers.
