Gaylene managed to miss her US Airlines flight back to LA this afternoon, largely because she thought she was on a United flight, and the slowness of the latter carrier's check-in service contributed to the mishap.
In the end it may have been a blessing in disguise, because it seems that her original flight was seriously delayed and she ended up leaving Phoenix before it did. Although she will miss her LA connection, there's a later one, so it should work out OK.
Meanwhile we saw Lisa from Canada at Terminal 2 with the now familiar wild-eyed look of someone who has recently misplaced their passport. So perhaps I wasn't the only loskop at the conference after all!
