I was dead last for a SIN-LHR flight because I had been flying SIN-FRA/AMS which leaves at 1155pm, compared to the LHR flight which leaves at 1130pm, and so got a little forgetful with the time. Then, the x-ray machine detected a Swisscard in my Samsonite rollerboard, I thought I had lost it as I hadn't seen it in a long long time.
Even with help from one of the agents, we couldn't find it in my suitcase, and even put it through the x-ray machine again to be sure. Finally found it wedged in a far, deep corner of one the front pockets which extended all the way down the length of the suitcse (I had always thought it was only halfway).
Eeps. Never again. I do not like being last/late. Sometimes, like Kiwi Flyer, I actually go early so that I can get savour my pre-departure drinks!
