Frontier Airlines has dropped some of its routes as low as $20 one-way for spring travel. It's possible to string together a roundtrip itinerary starting from $37 roundtrip and many routes can be found for under $100 roundtrip.
The sale is advertised for travel on Mondays through Saturdays, through April 17, 2019. Most routes are only flown on specific days of the week so you'll have to click around to find available flights.
Tickets must be booked by 11:59 pm ET, March 20, 2019.
All fares are nonstop and work in the reverse direction as well.
These fares all work in reverse and 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 $25-30 each way when purchased during the initial booking. Larger carry-on bag fees start at $30-35 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 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.
