If you have a carry-on bag that will fit under the seat in front of you, without causing any problems, you are allowed to store it there. However, it must fit under the seat, so that turbulence can not knock it free. Also if you prepay for your bag online prior to the flight, you will save 30% off the price. If you log onto SpiritAir.com and purchase your bag that way, it will only cost you $30 each way.
SpiritAir has raised it’s prices on checked bags and carry-on backs a few times in the past 12 months. A lot of people get angry over these added on prices, saying that they are deceiving. However airlines are not allowed to accept payment until they have let you know about these additional charges.
