Frontier Airlines has dropped some of its routes as low as $20 one-way for spring travel once again. Here's a city pair that's seeing those great sale prices, fly nonstop from St. Louis to Denver for $39 roundtrip. For those in Denver looking to check out St. Louis this deal is also available in reverse.
Travel Availability
Searching Frontier's site, I found seats at this price departing STL on Wednesday, May 1 with a return leg from DEN available on Wednesday, May 8, 2019.
Fares at this price are available on Tuesday, Wednesday, and Saturdays starting on April 30 through May 14, 2019. The travel window is small, but the savings are huge.
Baggage
This fare includes only 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.

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 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.
