After the most unbelievable experience at Bogota airport. The short version: Close your eyes and imagine a Central American airport, and an Iberia A340 Airbus that is 100%, yes 100% overbooked. 700-odd passengers for a plane that seats 350. And yours truly, with The Patent Upgrade Technique, managed to get himself taken to the head of the queue and thus got a seat. After that, the plane was only three and a half hours late. No kidding - it was as close to a riot as I've ever seen. Screaming, shouting, angry chanting, Iberia staff being jostled. Imagine the last helicopter out of the US Embassy in Saigon in 1975, and you're about there. <Takes deep breath: sips cold beer>
