Essentially 0: 1 in 2.2 * 10
27
But if we change it by a factor of 10 to 2,700,000-1, then it jumps to just 1 in 543.
The OP didn't distinguish between the big name airlines and smaller charter planes which have been much riskier, by like a factor of 10 IIRC. I don't know if this is still the case, but a few years ago they didn't have to conform to the same safety requirements. This was true even for airlines which by their name and colors seemed to just be extensions of a large airline, but in fact were run by completely different companies.
