Each checked bag can weigh 50 pounds or less and be 62 inches in size (length + width + height). What is considered excess baggage? To check more than two bags, each extra bag will result in an additional charge each way as long as it is no bigger than 62 inches (L+W+H) and weighs 50 lbs. or less.

For most major domestic and international airlines in 2026, the standard weight limit for a single checked bag is 50 pounds (23 kilograms) for economy class passengers. If a bag exceeds this limit, most carriers will charge a significant "overweight" fee, which can range from $100 to $200 per flight. For passengers in Premium Economy, Business, or First Class, as well as those with elite frequent flyer status, the limit is often higher, typically 70 pounds (32 kilograms) per bag. It is vital to note that even if you are willing to pay the overweight fee, most airlines have an "absolute maximum" of 70 or 100 pounds for a single bag due to occupational safety regulations designed to protect baggage handlers. Additionally, many budget carriers (like Ryanair or Spirit) require you to "pre-purchase" specific weight tiers, where the default might be as low as 33 or 44 pounds. Always verify your specific ticket’s "baggage allowance" in the airline’s app before heading to the airport to avoid expensive surprises at the check-in counter.
