Worst travel experience when coming back from holiday?

The jetlag flying from Sydney to LAX was horrible, but probably the worse was spending most of a day at the Houston Airport praying that our flight would not be cancelled. We got to the airport very early not so much for fear of flight cancellation but because of the warnings of potential flash flooding making the airport inaccessible. Heard a businessman coming off a plane say, "ah, as soon as they open that airplane door and I feel and smell that humidity, I know I'm home!"
