The very short Madrid to Barcelona flight was possibly the most confusing flight I've ever taken. First off, the flight leaves from Madrid's international terminal notwithstanding it's a domestic flight, so the driver understandably dropped us off at the domestic terminal and we had to lug our luggage around to the fairly far international terminal. Next we had to go through immigration, even though we weren't leaving the country. Even they seemed confused about this, as they exit stamped my passport and took my exit card away, but did nothing to Somchai's passport. We then boarded the Iberian flight to Barcelona. The only other time I flew Iberian was during my school trip, and I remember the elderly flight attendant hitting a customer because he knocked over her drinks cart when he opened the bathroom door, so I was a bit apprehensive. Fortunately no attendant on customer violence this trip, although business class was definitely not worth paying a peso more for, as it's just like economy class but separated with a curtain.

In Barcelona we went through immigration again, but the officer asked only one question, whether we had checked luggage, again a new immigration question for me. Since we had, he wouldn't let us through but told us to go upstairs. So we wandered around for about fifteen minutes until we found what looked to be a completely abandoned immigration post. Actually there was an officer sleeping inside. He didn't seem to care that I had already exited, and this time he took Somchai's card and stamped his passport with an exit stamp. So we now had both officially left Spain, although we still had four more days left in the country. This post led to a huge duty free shopping area, with no sign of a baggage carousel, but after another twenty minutes wandering around we started to go up and downstairs and came across a bunch of baggage carousels. Unfortunately none of them had our flight's luggage on them, and we were about to give up and just go to the hotel when Somchai spotted his bag on the carousel marked as a flight from Seville. So we found our luggage on this Seville flight, and fled the chaos to get to our hotel.
