Many people were waiting to see if other airlines would adopt the carry-on bag fee that Spirit Airlines implemented, and now they have their answer. Five of the major airline carriers have said they will not institute a similar fee. American Airlines, Delta Air Lines, JetBlue Airways, US Airways, and United Airlines have all said they will not charge a fee for carry-ons at this time. Other fees continue to build up, especially after a poor first quarter. Spirit Airlines, which is the main carrier out of Atlantic City, has said they will begin charge up to $45 for a carry-on if it needs to go into the overhead bin.
