The complaint also alleges that the merger is likely to result in higher ancillary fees, such as fees charged for checked bags and flight changes. In recent years, the airlines have introduced fees for those services, which were previously included in the price of a ticket. These fees have become huge profit centers for the airlines. In 2012, domestic airlines generated more than $6 billion in fees from checked bags and flight changes alone. The legacy carriers often match each other when one introduces or increases a fee, and if others do not match the initiating carrier tends to withdraw the change. By reducing the number of airlines, the merger will likely make it easier for the remaining carriers to coordinate fee increases, resulting in higher fees for consumers.
