Flying what I perceive to be a dangerous (or rather less than safe) airline really depends on how badly I want to go to a certain destination. There are some places in the world that are not really accessible any other way.

If I really felt that an airline was unsafe (if they had two or three crashes in the past 12 months for example), however, I would never fly it until its safety record improved over a period of time, regardless of the payment offered or how cheap the ticket price is. What's the point? For example, as much as I wanted to see certain parts of Mongolia a few years back, I just couldn't get myself to board a domestic MIAT flight and I didn't have time to spend an additional week overlanding to see the western part of the country. At the time, a couple of MIAT planes had just crashed. Instead I focused my touring on a part of the country that was more accessible by road. I figured I was young enough to get back to Mongolia some other time.

However, for the most part, there aren't many airlines that come to mind where I would have such an objection at the moment. I would probably think twice before flying domestically within certain countries, but I wouldn't have a problem flying Aeroflot internationally to Moscow or St Pb on its newer fleet. I would, however, try to avoid older aircraft from the former Soviet Union, if I had a choice, as I would be concerned about maintenance and spare parts availability with certain cash-strapped carriers.
