Was having lunch with a coworker who just returned from Houston, and she mentioned that her flight on Tuesday on Continental was on a 767. I disagreed, saying that in the eight years that I have been plying that route I had NEVER seen a 767 on it. Well, after she confirmed that it was a twin-aisle craft I decided to look it up on Flightaware:

Wow--a 764! Wonder what's up with that.
