¿Tengo que pagar por la asignación de asientos?

No, you do not have to purchase a seat assignement.

If you purchased a Basic Fare, a seat assignment is not included. You can choose to purchase a seat:

• At the time of booking
• After booking
• During check-in via the Frontier app or website

If you don’t purchase a seat, one will be randomly assigned to you at no charge — but your party may be seated separately.

Passengers with Economy Bundles  receive standard seating at no additional cost. Premium and Business bundles purchasers will receive other options. 

Frontier also offers fee-free family seating. You can find more details on our seating page
