Etihad, the national airline of the UAE, is currently promoting a discount code offering 10% off all flights (in all classes) in September 2014.
You simply need to book here, and then enter the Etihad discount code GRIP002 when prompted.
Plus, register here and you’ll earn double Etihad Guest points if you travel business class, and triple points in first class. This offer runs until 25 September, so you can combine it with the Etihad discount code.
It’s worth adding that you can earn airberlin topbonus points, as an alternative to earning Etihad Guest points, on Etihad flights. We recently highlighted what excellent value can sometimes be had with the airberlin topbonus frequent flyer programme.
Clearly this is a bad idea if you’d otherwise be eligible for double or triple Etihad Guest points (see above), but is worth thinking about if you’re not.
