In January, the Department of Transportation (DOT) reports it received 1,368 complaints about airline service from consumers, up 46.3 percent from the 935 complaints filed in January 2012, and up 51.8 percent from the 901 received in December 2012.
The DOT's Air Travel Consumer Report also said airlines reported two tarmac delays of more than three hours on domestic flights, but no tarmac delays of more than four hours on international flights in January.
The long domestic tarmac delays took place on January 27 and are under investigation by the Department. One of the tarmac delays took place on a flight departing Chicago O’Hare Airport and the other on a flight diverted to Bullhead City, Ariz.
The larger U.S. airlines have been required to file complete reports on their long tarmac delays for domestic flights since October 2008. Under a rule that took effect Aug. 23, 2011, all U.S. and foreign airlines operating at least one aircraft with 30 or more passenger seats must report lengthy tarmac delays at U.S. airports.
