Airlines Report Fourteen Tarmac Delays Over Three Hours on Domestic Flights, Two Tarmac Delays Longer Than Four Hours on International Flights in May
WASHINGTON – Airlines reported 14 tarmac delays of more than three hours on domestic flights and two tarmac delays of more than four hours on international flights in May, according to the U.S. Department of Transportation’s Air Travel Consumer Report released today. Ten of the reported tarmac delays involved flights departing from Houston on May 25 during severe weather. All of the reported tarmac delays are under investigation by the Department.
Airlines operating international flights may not allow tarmac delays at U.S. airports to last longer than four hours without giving passengers an opportunity to deplane. There is a separate three-hour limit on tarmac delays involving domestic flights. Exceptions to the time limits for both domestic and international flights are allowed only for safety, security, or air traffic control-related reasons. DOT rules require all U.S. and foreign airlines operating at least one aircraft with 30 or more passenger seats to report lengthy tarmac delays at U.S. airports.
In addition, the nation’s largest airlines posted an on-time arrival rate of 80.5 percent in May, up from the 76.9 percent on-time rate in May 2014, but down from the 81.8 percent mark in April 2015.
The consumer report also includes data on mishandled baggage, cancellations, chronically delayed flights, and the causes of flight delays filed with the Department’s Bureau of Transportation Statistics (BTS) by the reporting carriers. In addition, the consumer report contains statistics on aviation service complaints filed with DOT’s Aviation Consumer Protection Division by consumers regarding a range of issues such as flight problems, baggage, reservation and ticketing, refunds, consumer service, disability, and discrimination. The consumer report also includes reports of incidents involving the loss, death, or injury of animals traveling by air, as required to be filed by U.S. carriers.
In May, the reporting carriers canceled 1.1 percent of their scheduled domestic flights, an improvement over the 1.9 percent cancellation rate posted in May 2014, but up from the 0.9 percent rate in April 2015.
Chronically Delayed Flights
At the end of May, there were two flights that were chronically delayed – more than 30 minutes late more than 50 percent of the time – for two consecutive months. There were no chronically delayed flights for three consecutive months or more. A list of flights that were chronically delayed for a single month is available from BTS.
Causes of Flight Delays
In May, the carriers filing on-time performance data reported total delays of 19.5 percent – 5.34 percent of their flights were delayed by aviation system delays, compared to 5.36 percent in April; 6.62 percent by late-arriving aircraft, compared to 5.91 percent in April; 5.31 percent by factors within the airline’s control, such as maintenance or crew problems, compared to 5.09 percent in April; 0.73 percent by extreme weather, compared to 0.57 percent in April; and 0.03 percent for security reasons, compared to 0.02 percent in April. In addition, 1.15 percent of flights were canceled and 0.33 percent were diverted.
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 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 May, 35.21 percent of late flights were delayed by weather, up from 33.49 percent in May 2014 and from 29.93 percent in April 2015.
Detailed information on flight delays and their causes is available on the BTS site at http://www.bts.gov.
The U.S. carriers reporting flight delays and mishandled baggage data posted a mishandled baggage rate of 3.09 reports per 1,000 passengers in May, down from May 2014’s rate of 3.32, but up from April 2015’s rate of 2.93.
Incidents Involving Animals
In May, carriers reported 12 incidents involving the loss, injury, or death of animals while traveling by air, up from the six reports filed in in April 2015. April’s incidents involved the deaths of five animals and seven injured animals.
Complaints About Airline Service
In May, the Department received 1,492 complaints about airline service from consumers, up 16.4 percent from the total of 1,282 filed in May 2014 and up 5.4 percent from the 1,415 received in April 2015.
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 73 disability-related complaints in May, up from both the 65 complaints received in May 2014 and the 59 complaints received in April 2015.
Complaints About Discrimination
In May, the Department received two complaints alleging discrimination by airlines due to factors other than disability – such as race, religion, national origin, or sex – down from both the total of four recorded in May 2014 and the eight recorded in April 2015.
