If Spirit Airlines was an automobile dealer, the advertised sticker price on its cars would not include the charges for interior seats, windows, door locks, hood release, AC, heat, winshield wipers, a trunk, gas tank larger than 1 gallon capacity, hub caps, radio, cup holders, opperating manuals...... The car would contain only what is legally required by the state.
It would probably be similar to the Flinstone's family car....without seats.
Management should be embarrassed of their extra fee policies. Select this airlines only if there are no other options and if you are only carrying a toothbrush on your trip.
