I know what you mean. I was in Puerto Vallarta in February, my flight to Mexico city was cancelled due to civil unrest so we were stuck there for an additional 5 days. I blogged about the year before that, when my friend abandoned the homestead and I had to book emergency flights back home. The previous year all of my flights were cancelled the day before departure due to an industrial action in Germany. That might sound like I travel a lot, but in fact up to three years ago I hadn't left home in 7 years.
