U.S. airlines had 81.1 percent of their flights arrive on time in September, down 2.7 percentage points from September 2013, the U.S. Department of Transportation reported Thursday.
Hawaiian Airlines as usual topped the list, with 90.8 percent of its flights arriving on time or within 14 minutes of schedule. But that number was down 4.7 points from its September 2013 mark of 95.5 percent.
Southwest Airlines, which saw its on-time marks go down significantly after an August 2013 schedule change, improved 3.8 points in September compared to September 2013 and was one of only three airlines to improve its year-over-year results. However, it still finished 12th out of 14 U.S. airlines in the rankings.
American Airlines dropped 2.6 points to 81.1 percent to finish eighth. Merger partner US Airways fell 3.4 points year over year, but ended up sixth at 84.9 percent.
Among the largest carriers, Delta Airlines led the pack at 85.6 percent, just ahead of US Airways at fifth. But Delta’s on-time numbers were also off, down 4.7 points to 85.9 percent.
