Flights operated by the nation’s largest airlines arrived on time at a higher rate this past September than in either September of last year or in August 2009, according to the Air Travel Consumer Report released by the U.S. Department of Transportation (DOT).
The 19 carriers reporting on-time performance to the DOT, recorded an overall on-time arrival rate of 86.2 percent in September, higher than both September 2008’s 84.9 percent and August 2009’s 79.7 percent.
The DOT report also includes data on lengthy tarmac delays, flight cancellations and the causes of flight delays by the reporting carriers, as well as information on reports of mishandled baggage filed with the carriers, airline bumping and consumer service, disability and discrimination complaints received by DOT’s Aviation Consumer Protection Division.
The consumer report includes data on the number of domestic flights canceled by the reporting carriers. In September, the carriers canceled 0.6 percent of their scheduled domestic flights, a lower rate than both the 1.8 percent cancellation rate of September 2008 and the 1 percent rate posted in August 2009.
In September, the carriers filing on-time performance data reported that .0001 percent of their scheduled flights had tarmac delays of three hours or more, down from .012 percent in August. There were two flights with tarmac delays of four hours or more in September.
Causes of Flight Delays
In September, the carriers filing on-time performance data reported that 4.92 percent of their flights were delayed by aviation system delays, compared to 6.43 percent in August; 3.88 percent by late-arriving aircraft, compared to 6.45 percent in August; 3.89 percent by factors within the airline’s control, such as maintenance or crew problems, compared to 5.46 percent in July; 0.37 percent by extreme weather, compared to 0.69 percent in August; and 0.02 percent for security reasons, compared to 0.05 percent in August.
Weather is a factor in both the extreme-weather category and the aviation-system category. This includes delays due to the re-routing of flights by DOT’s Federal Aviation Administration in consultation with the carriers involved. Weather is also a factor in delays attributed to late-arriving aircraft, although airlines do not report specific causes in that category.
Data also shows the percentage of late flights delayed by weather, including those reported in either the category of extreme weather or included in National Aviation System delays. In September, 34.59 percent of late flights were delayed by weather, down 6.69 percent from September 2008, when 37.07 percent of late flights were delayed by weather, and down 11.92 percent from August when 39.27 percent of late flights were delayed by weather.
The U.S. carriers reporting flight delays and mishandled baggage data posted a mishandled baggage rate of 3.01 reports per 1,000 passengers in September, an improvement over both September 2008’s rate of 3.86 and August 2009’s 4.04 rate. For the first nine months of this year, the carriers posted a mishandled baggage rate of 3.94 per 1,000 passengers, down from the 5.42 rate posted during January-September 2008.
Carriers posted a bumping rate of 0.98 per 10,000 passengers for the quarter, down from the 1.03 rate for the third quarter of 2008. For the first nine months of this year, the carriers had a bumping rate of 1.22 per 10,000 passengers, up from the rate of 1.12 rate posted during the first nine months of 2008.
Incidents Involving Pets
In September, carriers reported four incidents involving the loss, death or injury of pets while traveling by air, up from both the zero reports filed in September 2008 and three in August 2009. All of September’s incidents involved pet deaths.
