June was the worst month of the year for airline on-time performance since December, according to the U.S. Department of Transportation. Together, U.S. airlines had an on-time arrival rate of 76.1 percent, down from 80.5 percent in May. But, they had fewer delayed flights than in June 2008.
Hawaiian Airlines put up the best on-time results in June, with Delta subsidiary Comair at the other end of the spectrum. Continental had the fewest delays among the legacy carriers (those that had a large footprint before airline deregulation in 1978), and American Airlines was at the bottom of the barrel for this category.
Unsurprisingly, weather, equipment problems and airport congestion were cited as the most frequent reasons for flight delays. To count as a delay, a flight must be more than 15 minutes late – canceled and diverted flights also count. Through most of the year, flight delays fell largely because airlines were cutting routes and servicing fewer passengers.
Mishandled baggage fell, as well, year-over-year, though it was up from May to June. Reports were down 20 percent from June 2008 to June 2009. AirTran had the fewest gripes from passenger. American Eagle (a unit of American Airlines) had the most.
