Has anyone out there actually flown in F and had F service on this route in the last year?
If not, I'd say the clue phone is ringing and some people are choosing not to pick up.
If you buy a ticket (or use miles), KNOWING by reading on these boards that they aren't really going to provide F class, and you're just looking to get something out of it, then that likely says something about your motives - so why whinge?
If no one has gotten the F service and the aircraft is continually changed by TG, and people know this and still complain, I think they need to either re-think their logic or have some brain imaging done.
