airman1900 - "In my opinion, insufficient training, respect for mountain flying by the airlines, bureaucrats, business jet owners and last but not least pilots are the culprits here."
Do you know what the training standards are? You seem to indicate that AA had, or has, the highest standards for the mountian flying.
How do you know the pilots don't take it seriously? I've been LPB, TGU, EGE, JAC, GUC qualified at various times. I've yet to fly with ANYONE that didn't take the challenge of flying into those cities extremely serious. Some would avoid the airports while others are attracted to the challenge.
