Ah, the good old schoolboy error of understanding probability and exposure. I think that the chap who sat next to me at primary school would disagree as his dad was killed in the Paris DC 10 crash. Perhaps his dad was very old!
If you look at the assumptions that you made at school, it might have assumed that you fly one return trip a year to Spain. So, lots of BA miles, but what are you going to redeem them on?
