FFF: "Therefore, the decision to buy this or that aircraft should rest with the people responsible for selling the tickets, and not the drivers."
When in the Southern Hemispheres a few months ago, I heard of an airline that still gave the pilots a big say in the selection of machines. I was told that the drivers asked for the biggest donkeys the machine could take. Understandable as one would want to have plenty of power in reserve... What it added to the purchase price was noticed later but was still agreed to.
They now have to be careful that those nice fat donkeys do not slurp too much go-juice.
