According to a new study conducted by FlightStats, a company that provides airline performance data, only 75.5% of Southwest flights arrive as scheduled, putting the carrier in 31st place when compared to other domestic carriers. JetBlue finished one place ahead with 78.56% of its flights arriving on time.
Top honors in the study go to Hawaiian Airlines, 95.28% of whose flights arrive as scheduled.
FlightStats ranked the airlines by tracking the performance of more than 150,000 flights per day from 43 domestic airlines. There were airlines that ranked below Southwest, but these were typically small local carriers that service limited areas. Penair, for example, the carrier that technically posted the lowest rating overall (only 42.53% of its flights arrive on time) is an Alaskan commuter airline that only travels to cities in Southern Alaska.
Generally speaking, domestic airlines posted a 82.58% on-time performance in September, down three percentage points from September last year. Additonally, cancellations were up significantly from last September's mark of 0.65%. There were 8,723 cancellations in September 2010 compated to 4,472 in Sept. 2009.
"It's a disturbing trend, and I can assure you our guys are on it," a Southwest spokesman told The Chicago Tribune when asked about why the company was below the reported average.
