Frontier’s Taxi Problem Isn’t the Airports its serves

Care to share?

We analyzed 2026 taxi times at US airports, and an alarming data point immediately stood out.  Frontier Airlines has a taxi time problem across the top ten US airports. How big is the problem?  These ten airports account for 21% of the airline’s flights. These top ten airports have an average taxi time of 36.1 minutes

. This problem can also be refined to show that this taxi time represents 21% of the total elapsed flight time.

US DOT data shows Frontier costs run at $143/minute.  The industry average taxi time is 27.6 minutes, so those 8.5 minutes could cost the airline $1,215.  Over the period tracked, there have been 14,461 Frontier flights.  Potentially $17.6m in extra taxi time.  Over four months, Frontier’s extra taxi time is worth about 20% of a heavily discounted A321neo’s list price (~$130m). (As they say, ‘prices may vary’)
