Penny fares are back on Frontier. This is as cheap as it gets. Frontier is selling flights for just 1 cent plus taxes on select routes and dates this spring. After taxes and mandatory fees, fares are just $15 one-way or $29 roundtrip.
Frontier even eliminated its online booking fee for these fares so this is the absolute lowest price you can get on these flights. Bag fees are extra unless you can travel with just a small backpack.
Travel on Tuesdays, Wednesdays, and Saturdays, through June 12, 2019, with a 7-day advanced purchase required.
Some routes will only have very limited availability at these rock-bottom fares and most routes are only flown on specific days of the week. Click on the fare details below for booking info.
Tickets must be booked by 11:59 pm ET, May 4, 2019.
All fares are nonstop and work in the reverse direction as well.
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.
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.
Seats will be assigned at random upon check-in for these prices. You may pay a fee to choose a specific seat.
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.
Searching Frontier's site, I found a flight departing Chicago ORD on Tuesday, June 4 returning from Nashville BNA on Tuesday, June 11, for $29 roundtrip.
