I mostly can't be bothered lugging a bag around the airport, so I throw myself on the tender mercies of the baggage mishandlers. I usually carry emergency stuff in my cabin bag, or course on my last trip to Philadelphia some last-minute packing mishap meant I forgot, so yeah, you guessed it, my bag went AWOL for two days. Luckily it did the mystery arrival the evening before I left Philadelphia for New York, however, I'd already bought spare clothes, chargers etc. They didn't quibble my claim (well, they said claim on your travel insurance and I said, no I don't think so). That was a direct flight, so I have no idea their excuse.
My strangest airport experience was in Ghana when on my way back home, as I was about to change my local currency I was led off by a group of gun-toting soldiers. I thought I'd committed some horrid crime but actually it turned they were rounding up foreigners to watch Nigeria's Got Talent. Apparently, one of their comrades was in it. We all agreed that he was very, very good and should have won.
