Flights operated by the nation’s largest airlines arrived on time at a lower rate this past October than in either October of last year or in September 2009, according to the Air Travel Consumer Report released today by the U.S. Department of Transportation (DOT).

According to information filed with the Bureau of Transportation Statistics (BTS), a part of DOT’s Research and Innovative Technology Administration (RITA), the 19 carriers reporting on-time performance recorded an overall on-time arrival rate of 77.3 percent in October, a lower rate than both October 2008’s 86.0 percent and September 2009’s 86.2 percent.

The monthly report also includes data on lengthy tarmac delays, flight cancellations and the causes of flight delays by the reporting carriers, as well as reports of mishandled baggage filed 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.
