Got off on the wrong island in Spain, "Gran Canaria" thinking "ok, Canary Islands" without realizing I was going to Tenerife. Ended up waiting for my luggage for two hours then having an Iberia CS agent tell me my error. Luckily(?), I was able to get a flight to Tenerife within an hour.

The flight went to Tenerife South airport while my luggage had landed at the North airport. Luck had it that public transportation was down due to one of the nuemerous dias festivos, so ended up paying $82 for a taxi to the North (in 1991 dollars on a student budget). Didn't have enough money for a hotel so begged the taxi driver to help me find a place and bargain the price down. He helped out and I lived off of bread and ham for a week.

Best time of my life, btw.
