Unless you are into taking journeys for the sake of it then its mile for mile that matters
Miles are irrelevant, the statistic could get you on your first or last journey. Could be Australia, could LHR-MAN. Irrelevant. As soon as I step on board my chances of dying are 1 in 85,000,000. As soon as I get in my car the chances of dying are 1 in 330,000,000.
The major difference being how quickly I ramped up the number of journeys. Obviously the more journeys the quicker statistically I will meet my maker. Doesn't change the basic premise though, cars are safer.
Ryanair, Easyjet, Air Berlin, Norwegian, Wizz Air you will never have an accident, because statistically they are 100% safe ...
Air Berlin and Ryanair have had accidents but no fatalities as far as I am aware. Not quite the same.
