Seat Assignments

Seats will be assigned at random upon check-in for these prices. You may pay a fee to choose a specific seat.

Alternate Fares

Frontier offers the Works bundle, which can be added to any flight during the initial booking. It includes a standard carry-on bag plus a personal item, one free checked bag, seat selection (including stretch seating), priority boarding, flight flexibility, and refundability. This is a value if you want all of these amenities, but chances are you can get away with just adding what you need à la carte for cheaper.

Example Booking

Searching Frontier's site, I found a flight departing Indianapolis IND on Monday, February 3, returning from Cancun CUN on Monday, February 10, for $166 roundtrip.
