I fly Etihad quite regular, even a member, couple of years ago it was advertised so got 10% off... Not heard of it since and only just got back from flying Etihad yesterday.
Like a lot of companies when "Etihad airways" wanted to get their name out in lights they had great offers and good customer service, now that they have grown they have withdrawn lots of benefits, lowered air mile bonuses and generally show they don't really care for their members.
As far as I know you don't get 10% off any longer, if there are offers on it is "categorised" flights only ( which are expensive ). As you can tell they have you over a barrel..
