2 miles/EUR spent or 10% off on booking.com?
As you probably noticed, when you book hotels on booking.com via Aegean there is no option to log in, as you do have when book thru KLM or LH. So due to this reason, I cannot get my 10% off (genius s**t) but I get 2 miles/EUR spent, while KLM and LH gives you 10% off but 1 mile/EUR.
What are you choosing?
