NOTES: The tarmac delay rulemaking took effect in October 2008. January 2009 includes one flight with two separate 3-hour tarmac times. Northwest Flight 1491 on Jan. 28 was on the tarmac for 188 minutes before returning to the gate. The flight departed the gate a second time and was on the tarmac for 199 minutes before wheels-off. Details of the flight are listed as a 3-hour multiple gate departure and a 3-hour taxi-out. Table 12 of the Air Travel Consumer Report lists number of flights with 3-hour tarmac times and counts NW Flight 1491 as a single flight. Beginning in April 2010, carriers were subject to fines for 3-hour-or-more tarmac times.

Explanation of Stage of Operation:

Prior to Cancellation: Flight left the gate but was cancelled at the origin airport.

Multiple Gate Departure: Flight left the gate, then returned and then left again to resume normal operation. Tarmac time is the time before the return to the gate.

Taxi-out: The time between gate departure and wheels-off.

Taxi-in: The time between wheels-on and gate arrival.

At Diversion Airport: The tarmac time at the alternate airport.
