Etihad has been very aggressive in buying stakes in airlines around the world and this has led to it setting up an alliance like network of its own known as Etihad Airways Partners. The biggest benefit of this partner network is like other airline alliances; you can easily avail reciprocal benefits and earn miles when flying each on a program of your choice. The latest of the Etihad partners to connect together to offer reciprocal benefits are airberlin & Jet Airways.
Starting 1st of June 2015, Airberlin Topbonus and Jet Airways JetPrivilege members are eligible to earn miles on flights with each other and to sweeten the deal; airberlin is offering double miles on all Jet Airways flights undertaken until 15th of August 2015. Do note that you need to register first to avail this offer; the registration page for the offer can be found here.
I have a few flights coming up with Jet Airways that am thinking of crediting to airberlin to take advantage of the double miles promo and also make good of the miles needed to maintain my airberlin status which also helps me access Oneworld lounges across the world of which airberlin is a member.
