Frontier Fares from $20 One-way or $39+ Roundtrip

Take advantage of the latest Frontier Airlines sale with many new fares priced as low as $20 one-way. Though we have seen this sale on a nearly weekly basis lately, we do see a few new routes added each week and it's likely these super low fares will soon be more scarce as we head into the peak summer travel season. Roundtrip itineraries are available starting from $39 and many routes can be found for under $100 roundtrip.

Travel Availability

The sale is advertised for travel Mondays through Saturdays, through May 15, 2019. Even so, we've found some of these low fares available for travel dates later in May or into early June.

Most routes are only flown on specific days of the week so you'll have to click around to find available flights. A 3-day advanced purchase is required.

Sale Period

Tickets must be booked by 11:59 pm ET, April 24, 2019.

There are many more routes available for under $100 roundtrip. Lowest fares may not be available throughout the entire travel period. You'll have to decline all extras to get the lowest price.

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.

Example Booking

Searching Frontier's site, I found flights departing San Diego SAN on Monday, May 6, returning from Las Vegas LAS on Thursday, May 9 for $39 roundtrip.
