There's been a big turnaround for Frontier Airlines.  It landed near the top for on-time arrivals, according to the latest Air Travel Consumer Report from the U.S. Department of Transportation, and consumer complaints lodged against the Denver-based airline have also dropped significantly.

In February 2015, Frontier flights arrived on time 58.8 percent of the time, placing the airline second from last in that category. This year in February, 87.3 percent of its flights were on time, and it moved up to 4th among all major U.S. airlines.  Frontier says it focused on getting the first flight of the day on-time to avoid a cascade effect on later flights.

In the on-time category, Hawaiian Airlines flights had the best record, 91.3 percent. Spirit was last, with 63.2 percent.

When it came to consumer satisfaction, Frontier also showed a big improvement. In February 2015, there were 123 complaints lodged against the airline, compared to 39 in the same month this year. That's a drop of about 70 percent.  Frontier blamed the spike in complaints last year on a restructuring of the company, after it was taken private in 2013 and steered toward becoming an ultra-low cost carrier. 

The most complaints in the February 2016 time period, 390, were lodged against American Airlines. Four airlines shared the least number of complaints, 5: Dynamic Airways, ExpressJet, Mesa Airlines and SkyWest Airlines.
