So you want to be able to pick a flight based on the number of hours the guys at the pointy end have?
Hypothetical situation. You see flight 1.) crewed by a 1500hr F/O and a 5000hr Cpt or flight 2.) crewed by a 7000hr f/o and 10000hr Cpt. Which do you chose based on that information?
How does that information tell you that flight one have actually dealt with, handled and safely executed a real emergency whereas flight 2 have never had any such thing.
Also when you get in a cab is the guy likely to say "yeah guv, I had a massive smash just last week." Is he hell as like.....
