I’ve sat myself down on the wrong aircraft and got picked up on the headcount. It was in Budapest, in Communist days, and the level of security and scrutiny was very high, which made it all the more remarkable. I was with my two kids and we were the last to leave the lounge, having faffed about trying to spend the last of our Hungarian currency. Seems that the gate led to a Y-shaped airbridge and the corridor to our flight (Brussels) was already closed off – we just followed the other one and found an identical aeroplane (Malev Tu-134) to the one we were expecting. The crew waved us on board, we found our seats and sat down. Seems we were on the Zurich flight. Luckily it was sorted before either flight departed.
