MIAMI— Denver-based ultra-low-cost carrier Frontier Airlines has taken delivery of its first Airbus A321, hence becoming the sole operator in North America to have operated all Airbus A320 family aircraft variants.

“All of us at Team Frontier are excited to welcome our first A321 into our family of Airbus aircraft,” said Barry Biffle, President – Frontier Airlines. “The A321 is the perfect complement to our fleet as we continue to seek areas of growth and offer our customers Low Fares Done Right.”

The new single-class 230-seat airliner will initially be used on their routes from Orlando to Philadelphia, Denver, Cleveland and Detroit. Frontier opened up a new crew base in Orlando to support the A320 family’s largest type.

Frontier has relied its growth on an all-Airbus fleet, comprised initially by A318, A319, and
A320 aircraft. Currently, Frontier’s in-service fleet consists of 57 A320 Family aircraft (35 A319s and 22 A320s). In addition to the remaining 18 A321s on backlog, the airline has 18 A319neo (new engine option), 62 A320neo, and two A320ceo aircraft on order, for a total backlog of 100 Airbus single-aisles.

A year after Republic Airways sold Frontier to Phoenix-based equity firm Indigo Partners, the airline has gone through a transition from a low-cost carrier to an ultra-low-cost carrier with a turbulent outcome. By last May, its missteps led to a wave of customer complaints, federal reports raking it as the worst on-time performance among US carriers and a sudden change of top management.
