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 77.8 percent in July, up from both the 76.7 percent on-time rate of July 2010 and June 2011�s 76.9 percent rate.

The monthly report also includes data on lengthy tarmac delays, 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.

Tarmac Delays
The carriers filing on-time performance with the Department reported only one tarmac delay of more than three hours in July, compared to three in July 2010 and 14 in June 2011.

Cancellations
During July, the carriers canceled 1.7 percent of their scheduled domestic flights, up from July 2010�s 1.4 percent cancellation rate but down from June 2011�s 1.8 percent.

Chronically Delayed Flights
At the end of July, there was 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 34 flights that were chronically delayed for two consecutive months. There were no chronically delayed flights for four consecutive months or more. A list of flights that were chronically delayed for a single month is available from BTS (www.bts.gov).

Causes of Flight Delays
In July, the carriers filing on-time performance data reported that 5.69 percent of their flights were delayed by aviation system delays, compared to 6.06 percent in June; 7.99 percent by late-arriving aircraft, compared to 8.15 percent in June; 5.84 percent by factors within the airline�s control, such as maintenance or crew problems, compared to 6.10 percent in June; 0.64 percent by extreme weather, compared to 0.67 percent in June; and 0.03 percent for security reasons, compared to 0.04 percent in June. 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 July, 38.21 percent of late flights were delayed by weather, up 1.60 percent from July 2010, when 37.61 percent of late flights were delayed by weather, and up 4.11 percent from June when 36.70 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 www.bts.gov.

Mishandled Baggage
The U.S. carriers reporting flight delays and mishandled baggage data posted a mishandled baggage rate of 3.71 reports per 1,000 passengers in July, up from both July 2010�s rate of 3.69 and June 2011�s rate of 3.57.

Incidents Involving Pets
In July, carriers reported six incidents involving the loss, death or injury of pets while traveling by air, down from the eight reports filed in July 2010, but up from the five reports filed in June 2011. July�s incidents involved the deaths of five pets and the injury of one pet.

Complaints About Airline Service
In July, the Department received 1,285 complaints about airline service from consumers, up 17.1 percent from the 1,097 complaints filed in July 2010, and up 14.0 percent from the 1,127 received in June 2011.

Complaints About Treatment of Disabled Passengers
The report also contains a tabulation of complaints filed with DOT in July against airlines regarding the treatment of passengers with disabilities.  The Department received a total of 56 disability-related complaints in July, up from both the total of 31 complaints filed in July 2010 and the 48 complaints received in June 2011.

Complaints About Discrimination
In July, the Department received five complaints alleging discrimination by airlines due to factors other than disability � such as race, religion, national origin or sex � down from the total of 12 recorded in both July 2010 and June 2011.
