Nearly all the crashes of commercial airlines are puddle jumpers flown by relatively inexperienced pilots flying relatively unreliable aircraft in relatively unreliable weather conditions. And the more remote you get from US airlines the more dangerous your flight would be.
I would not, for instance, fly on Aero Mexico or Peruvian Airlines or any Middle Eastern airline other than El Al. And for obvious reasons there is no way on earth I would get on a Malaysian Airlines flight to anywhere. I think they are done.
Still, even those airlines are safer, per passenger mile, than any other mode of transportation.
In my younger (and more foolish) days I flew Air Tanzania,Egypt Air,Air Malawi and several other airlines whose names I've blocked out.But today I agree with you up to a point...that is,I've flown Emirates several times and have had a great experience each time.But Aero Mexico or Aero Peru? No way,Jose!
