US airline performance slips

The U.S.’ largest airlines recorded a lower rate of on-time flights and a higher rate of mishandled baggage and canceled flights this past June than during either this past May or the previous June, according to the Air Travel Consumer Report released today by the U.S. Department of Transportation (DOT). The report also shows that consumer complaints against air carriers rose in June compared to the same previous months.

According to information filed with the Bureau of Transportation Statistics (BTS), a part of DOTs Research and Innovative Technology Administration (RITA), the 20 carriers reporting on-time performance recorded an overall on-time arrival rate of 68.1 percent in June, down from both June 2006s 72.8 percent and May 2007s 77.9 percent. The data also show that these carriers canceled 2.7 percent of their domestic scheduled flights in June, up from both June 2006s cancellation rate of 1.7 percent and May 2007s 1.1 percent.

The 20 reporting carriers also posted a mishandled baggage rate of 7.92 reports per 1,000 passengers in June, higher than both June 2006s 6.30 rate and May 2007s 5.93 mark.

In addition, the Department received 1,094 complaints from consumers in June about airline service, up 43.4 percent from the 763 complaints received in June 2006 and 17.8 percent more than the total of 929 filed in May 2007.

The monthly report also includes data on causes of flight delays, airline bumping, and consumer disability and discrimination complaints received by DOTs Aviation Consumer Protection Division. This report also includes reports required to be filed by U.S. carriers of incidents involving pets traveling by air.


Causes of Flight Delays

The carriers filing on-time performance data reported that 9.13 percent of their June flights were delayed by aviation system delays, compared to 7.49 percent in May 2007; 10.04 percent by late-arriving aircraft, compared to 6.71 percent in May; 8.13 percent by factors within the airlines control, such as maintenance or crew problems, compared to 5.76 percent in May; 1.42 percent by extreme weather, compared to 0.76 in May; and 0.09 percent for security reasons, compared to 0.06 percent in May. 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 DOTs 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 collected by BTS 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 June, 44.97 percent of late flights were delayed by weather, up 6.92 percent from June 2006, when 42.06 percent of late flights were delayed by weather, and up 14.78 percent from May when 39.18 percent of late flights were delayed by weather.

Detailed information on flight delays and their causes is available on the BTS site on the World Wide Web at . For example, that site shows that airlines reported 462 flights with taxi-out times of more than three hours in June. More details by carrier and by airport are available on the BTS website at /.
