Thanks for the reply.
It's a pity that there aren't more solid facts on the cost savings you give.
Although the techniques you have mentioned to 'make or break the airline' could be seen as just normal practices could they not?
Why would a pilot not choose an optimul altitude? Is it true the computers will tell you this anyway? (not having a shot at the skill involved in flying an aircraft)
But what is the difference in pilot A following standard procedure and pilot B also following standard procedure ? Are there secret better procedures ?
