Are you suggesting that people should withdraw their right to complain? That we should just toddle off to another airline, or meekly accept the changes without making a fuss?
I have personally given my feedback to Skywards and suggest others do as well if they are unhappy with any aspect of the programme.
The most powerful message is of course to vote with your wallet, as this is the only way to genuinely command attention, but to say and do nothing will achieve nothing.
