I'm sorry - if someone is so annoyed by to the point that they will take some of their business elsewhere, and will write and complain (on here and to the airline) yet will not fly DJ or SQ even in in protest, then QF know they're not going to lose too much money out of this.
SQ is not the only competitor on the route, as you would be well aware.
Regarding DJ, I am refusing to fly DJ in protest more than I would refuse to fly QF in protest.
It is merely the matter 'no point in having QF as a preferred carrier'.
If you do the math on your $25,000. That's $160 x 156 Forgetting the premium seats on the A380s, and assuming there are 8 seats on the 747 that can be paid for like this, that's 19 747 flights to Europe/US/SA/Arg. Or about 1 days worth. Then there's the myriad A330 flights around Asia.
It assumes that they will be mostly sold. I doubt they would, somehow, especially the middle ones.
Besides, you are forgetting the fact that I am not objecting to the fees. I think it's possibly a good idea (although I have seen a lot of pitfalls of 'selling exit row seat' in practice and it has to be managed properly), in fact. All I am objecting to is the removal of WP priority.
They could have double-dipped by giving WPs priority access prior to 7 days, and still got the fees AND kept my long haul business (I may even part with $160 to get the exit row in business class if I am likely to have a 'neighbour' so that I do not need to step over them in 'bed config').
So, in my case it would be about the 'straight lost revenue' - my objection is only about removing priority from WPs, and charging for exit row seat is not an issue as far as I am concerned, although I hope this is not the start of generalised LCC-esq behaviour from QF.
There may be a day when I do not wish to fly QF domestic as well, if things get worse - so far, I would like to avoid SQ and DJ more than I would like to avoid QF. It is not as if I am asking anyone to do the same so I am not sure why you find this objectionable.
I guess I'm in the minority here that the fees are not my issue - it's merely the erosion of WP privileges that I suspsect will continue.
