Beginning in April 2026, prominent United States airlines implemented substantial fee increases for checked luggage, largely driven by rising fuel expenses and operational costs. Most major carriers now charge approximately $45 for the first bag and $55 for the second, though prices are often higher for travelers who do not prepay online. The data reveals that even Southwest Airlines has moved away from its traditional free baggage policy, joining competitors like Delta and United in charging for domestic luggage. Some companies, such as JetBlue, have adopted dynamic pricing models that fluctuate based on demand and travel dates. To bypass these new costs, passengers are encouraged to utilize co-branded credit cards, maintain loyalty status, or book premium cabin tickets. Strict adherence to carry-on dimensions remains a vital strategy for budget-conscious travelers seeking to avoid these updated surcharges.
