I too have made a few flights over the pond. It is amazing how much trust we place in air travel--I know, I know--it's the safest form of travel, but when you think about a very simple problem that can kill all aboard, the danger involved becomes real...Ahh, it'll never happen to me...
I always figured the odds...figured I could sit at home scared or go with the odds and see the world. Worked out great!
Mine were all over the Pacific to places like Narita, Singapore or Australia......tons of long-haul time to think about such things if that's the mindset. I hate those little seatback GPS thingies that tell you that you "only" have 13 hours to your destination.
As I always say, there is no such thing as an Atheist on a crashing Airplane.
Take it to the Bank.
It's just that you can use up a lot more miles in one hour than you can on the road. Not to mention that when the plane crashes, the consequences are a lot more dire.
