Amazon is not the only company having a prime day for sales. Frontier Airlines just posted one of its biggest sales ever. It claims to have 3 million seats on sale with fares as low as $20 one-way or $39 roundtrip.

While Frontier is an ultra-low-cost carrier with extra fees for everything from snacks to a carry-on bag, these ultra-low fares can still save a lot of money as long as you know what you are getting and purchase any necessary extras in advance.

Baggage

These fares only include one small personal item. Checked bag fees start at $30 each way when purchased during the initial booking. Larger carry-on bag fees start at $35 each way.

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 a la carte for cheaper.
