Low-fare carrier Frontier Airlines is offering 90% off fares to nearly all of its more than 100 destinations in the U.S. and Puerto Rico. The offer includes two million seats that are on sale across Frontier’s network including to all major U.S. destinations like Miami, Las Vegas, Los Angeles, New York City, Orlando, and Phoenix.

Frontier’s 90% off sale is available until 11:59 p.m. ET on March 16, 2020. Promotion code SAVE90 must be used at the time of booking. Tickets are available now at

In addition, Frontier is allowing those who book tickets issued March 10 through March 31, 2020, to make a one-time change to their itinerary without a change/cancel fee by contacting Frontier at (801)401-9000. As always, no change fees apply 60 days or more before departure.

Frontier operates over 95 A320 family aircraft and has the largest A320neo fleet in the U.S., delivering the highest level of noise reduction and fuel-efficiency, compared to previous models. The use of these aircraft, Frontier’s seating configuration, weight-saving tactics and baggage process have all contributed to the airline’s average of 39% fuel savings compared to other U.S. airlines (fuel savings is based on Frontier Airlines 2018 fuel consumption per seat-mile compared to the weighted average of major U.S. airlines), which makes Frontier the most fuel-efficient U.S. airline.
