From CNBC:

Airlines, including United, American, and JetBlue, are increasing fees for checking bags. Prices vary depending on when you pay, with a higher cost if you check your bags at the airport. The goal is to encourage travelers to pay in advance, freeing up check-in staff and speeding up the boarding process. American Airlines recently raised their checked bag fees, with exemptions for certain customers.

Airlines are raising baggage fees due to higher costs such as labor and fuel. U.S. airlines made over $5.4 billion from baggage fees in the first nine months of 2023. Southwest Airlines remains an outlier by allowing customers to check two bags for free, aiming to improve efficiency and customer satisfaction. Airlines like JetBlue cite the need to cover increased expenses and keep base fares low.
