The nation’s largest airlines posted an on-time arrival mark in May that was an improvement from April’s showing but down from the performance recorded in May 2010, according to the Air Travel Consumer Report released today by the U.S. Department of Transportation (DOT).
Information filed with the Bureau of Transportation Statistics (BTS), a part of DOT’s Research and Innovative Technology Administration, shows that the 16 carriers reporting on-time performance recorded an overall on-time arrival rate of 77.1 percent in May, down from the 79.9 percent on-time rate of May 2010 but up from April 2011’s 75.5 percent rate.
The monthly report also includes data on lengthy tarmac delays, on-time performance, chronically delayed flights, flight cancellations, and the causes of flight delays filed with the Department by the reporting carriers. In addition, the report contains information on reports of mishandled baggage filed by consumers with the carriers, and consumer service, disability and discrimination complaints received by DOT’s Aviation Consumer Protection Division. This report also includes reports of incidents involving pets traveling by air, as required to be filed by U.S. carriers.
The carriers filing on-time performance with the Department reported 16 total tarmac delays of more than three hours reported in May by the airlines that file on-time performance data with DOT, compared to one in May 2010 and four in April 2011.
Fourteen of the delays involved American Eagle Airlines flights arriving at Chicago’s O’Hare airport on May 29, a day in which the Chicago area experienced weather issues. The other two long tarmac delays involved an American Eagle flight from New York JFK to Indianapolis on May 26, and a May 11 Southwest Airlines flight from Denver to Seattle. All of the reported tarmac delays are under investigation by the Department.
During May, the carriers canceled 2.1 percent of their scheduled domestic flights, compared to 1.2 percent in May 2010 and 2.0 percent in April 2011.
Chronically Delayed Flights
At the end of May, there was only one flight that was chronically delayed – more than 30 minutes late more than 50 percent of the time – for three consecutive months. There were an additional 46 flights that were chronically delayed for two consecutive months. There were no chronically delayed flights for four consecutive months or more.
Causes of Flight Delays
In May, the carriers filing on-time performance data reported that 6.67 percent of their flights were delayed by aviation system delays, compared to 7.57 percent in April; 7.71 percent by late-arriving aircraft, compared to 8.35 percent in April; 5.47 percent by factors within the airline’s control, such as maintenance or crew problems, compared to 5.68 percent in April; 0.68 percent by extreme weather, compared to 0.55 percent in April; and 0.05 percent for security reasons, compared to 0.04 percent in April. 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 collected by BTS also show 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 May, 42.45 percent of late flights were delayed by weather, up 8.37 percent from May 2010, when 39.17 percent of late flights were delayed by weather, and up 6.47 percent from April when 39.87 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 3.52 reports per 1,000 passengers in May, up from both May 2010’s rate of 3.23 and April 2011’s rate of 3.24.
Incidents Involving Pets
In May, carriers reported two incidents involving the loss, death or injury of pets while traveling by air, down from the three reports filed in May 2010 and four reports filed in April 2011. May’s incidents involved the death of one pet and the injury of one pet.
Complaints About Airline Service
In May, the Department received 1,062 complaints about airline service from consumers, up 32.9 percent from the 799 complaints filed in May 2010, and up 20.8 percent from the 879 received in April 2011.
Complaints About Treatment of Disabled Passengers
The report also contains a tabulation of complaints filed with DOT in May against airlines regarding the treatment of passengers with disabilities. The Department received a total of 57 disability-related complaints in May, up from both the total of 40 complaints filed in May 2010 and the 54 complaints received in April 2011.
Complaints About Discrimination
In May, the Department received 10 complaints alleging discrimination by airlines due to factors other than disability – such as race, religion, national origin or sex – equal to the total of 10 recorded in both May 2010 and April 2011.
Consumers may file their complaints in writing with the Aviation Consumer Protection Division, U.S. Department of Transportation, C-75, W96-432, 1200 New Jersey Ave. SE, Washington, DC 20590; by voice mail at (202) 366-2220 or by TTY at (202) 366-0511.
Consumers who want on-time performance data for specific flights should call their airline’s reservation number or their travel agent. This information is available on the computerized reservation systems used by these agents. The information is also available on the appropriate carrier’s website.
