Given all the things I do in life, I can safely say that the relative difference in risk between airlines is not worth wasting a second's thought on.

The only risky things I've done relating to aviation have been in single-engine prop-driven planes: an aerial tourist flight over the Nazca Lines, a Namibian bush pilot who did a 180deg turn at such a low altitude she was "watching out for the telegraph poles", and a seaplane in Idaho.

Much riskier was getting to Battambang airport in Cambodia on the back of a motorbike with a 20kg rucksack & no helmet. Oh, and driving a Bajaj Autorickshaw 4000km across India...
