- American, JetBlue and Alaska have all raised baggage fees this year.
- Carriers have changed the price to check a bag depending on whether travelers pay for it in advance or at the airport.
- Airlines and other companies have been grappling with how to grow profits while reining in costs, such as new labor contracts.
Also if I remember right, any unused space can be used by FedEx/UPS to move packages and the airliners get more money from that than passenger’s bags
