A quarter of all of Frontier Airlines’ flights did not arrive on time in November, according to a government report released on Friday.
The Denver-based low-cost carrier posted an on-time rate of 74.0 percent, the worst of any U.S. carrier. Hawaiian Airlines had the best on-time performance rate with 93.9 percent of its flights arriving on time.
Frontier said it has been working to improve its operations and expects its December and January on-time rates to be higher.
“We’ve been working hard focusing on on-time performance especially with our Headstart program which focuses on making sure that the first flight of the day leaves on time as this will impact the operation throughout the day,” the airline said in a statement. “Our December [on-time] numbers will be higher than November, and January, so far, is trending in the 80s.”
The Bureau of Transportation Statistics reported that 83.7 percent of airlines’ flights were on time in November, up from the 80.6 percent reported in November 2014, but down from the 87 percent reported in October 2015.
Fort Worth-based American Airlines ranked fifth with an on-time rate of 83.7 percent while Dallas-based Southwest Airlines ranked seventh with an on-time rate of 83.3 percent.
American’s regional subsidiary, Envoy Air had the highest rate of canceled flights, with 4.5 percent of its schedule canceled in November. Delta Air Lines, once again, had the lowest rate of canceled flights as it only canceled 14 flights in the entire month.
There were five domestic flights delayed more than three hours during the month. Alaska Airlines flight 154 from Kotzebue, Alaska to Anchorage had the longest delay, sitting on the tarmac for 260 minutes.
Airlines improved their mishandled baggage rate to 2.58 reports per 1,00 passengers, down from 2.87 in November 2014. However, complaints were up 43 percent as the U.S. Department of Transportation received 1,308 complaints about airline service.
