Here is my 2010 travel summary:
113,635 miles, 7 airlines, 32 airports.

The winner of the most outrageous reason for a delay is United Airlines. We were sitting on the active taxiway, in line for takeoff when the pilot came on and said that we had to return to the gate to pick up a crew member who needed to be at the airport for a morning flight. The delay ended up being 61 minutes for a flight that was scheduled to be 1 hr 23 minutes, gate to gate.
Compared to 2009, my stats are actually worse in 2010. Sadly, the FAA Reauthorization funding has been delayed yet again (I think it is on it's 14th extension) so until the system improves, airline passenger's will continue to face long delays, wasted time, and unreliable service from the air carriers. There is a lot in the airlines control, although I have seen very little effort to determine what that is and make the most of customer experience.
