If you want to travel with Spirit Airlines and want to book a first-class seat, you may not be alone. Spirit is a budget airline and they don’t provide a traditional first-class cabin, they do offer a comfortable upgrade. Instead of a First Class service, Spirit Airlines provides the "Big Front Seat," which has a larger seat that includes more space and extra legroom. For those looking to travel with a higher level of comfort, Spirit Airlines First Class is not part of their offerings. Still, the Big Front Seat can give you a similar experience with priority boarding and added comfort for a fraction of the cost. Many passengers choose this option for the extra comfort it offers without the high cost of First Class tickets.
