Note: Numbers found here may differ from those previously available on the BTS website and on the Air Travel Consumer Report. Beginning with the release of May 2010 data, lengthy tarmac times are measured as more than 3 hours (181 minutes plus). Previous releases used the measurement of 3 hours or more (180 minutes plus). 2-hour and 1-hour tarmac times have been changed to conform. Data from previous months on this application have been revised but may differ from the previously-released Air Travel Consumer Report Tables 11 and 12, which were not revised. Air Travel Consumer Report Tables 11 and 12, beginning with the release of May 2010 data in the July report, will reflect the change in measurement.
