Frontier Airlines has another round of penny fares (+tax) this week. After taxes and mandatory fees, we're seeing around 80 routes with fares starting around $15 one-way or $29 roundtrip.

Frontier even eliminated its online booking fee for these super-low fares, so this is the absolute lowest price you can get on these flights that are $29 roundtrip or less. Slightly higher fares may have a small online booking fee, but not enough to make a trip to the airport worth the savings. Bag fees are extra unless you can travel with just a small backpack.

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 Minneapolis MSP on Tuesday, October 1, returning from Colorado Springs COS on Tuesday, October 8, for $29 roundtrip.


There isn't an online booking fee (carrier interface charge) for this fare, and therefore, it won't be any cheaper at the airport.
