Qatar Airways:
Business travel:
CEO = firm F everywhere
Senior Executive = firm J everywhere, upgrade to F if seats available
Executive = firm Y everywhere, upgrade to the highest of F or J when there are seats available
Manager = firm Y everywhere, upgrade to J (long haul) or F (short haul) when there are seats available
Staff = firm Y everywhere, upgrade to J on flights longer than six hours when there are seats available
Senior Captain = as Executive
Other Flight Crew = as Manager
Cabin Crew = as Staff
Only the CEO and Senior Executives can take F or J when a revenue ticket needs to be purchased
I used to travel a day or two early or late when more convenient flights were forecast to be full. Not everybody could get away with this though!
Leisure travel:
CEO, Senior Executive, Executive and Senior Captain can buy industry tickets in F, J or Y
Manager and other Flight Crew can buy industry tickets in J or Y
Staff and Cabin Crew can buy industry tickets in Y

Company manual:
W where available, Y otherwise
In practice:
Fly in the same cabin as the Client when travelling together
Fly in J on a paid project if the Client is paying or the price is not unreasonable compared with W
Fly in F if the fare is not unreasonable compared with J or W (e.g. because BA are doing a buy-J-get-F offer)
