To celebrate the newest member of the alliance not only are Airberlin Topbonus members getting double miles on Oneworld alliance flights, but also all Oneworld carriers are offering double miles for Airberlin flights.
Oneworld made an announcement about this:
Members of American Airlines, British Airways, Cathay Pacific, Finnair, Iberia, Japan Airlines, LAN Airlines, Qantas, Royal Jordanian and S7’s frequent flyer programmes will earn double the normal mileage awards when flying on eligible airberlin flights from today until 15 May 2012.
Now here’s the tricky part. Some of the airlines require you to register for this double miles promotion and some do not. I went just through all the websites to find more information.
American Airlines AAdvantage: You need to register to get double miles credited for Airberlin flights. You can do it here.
British Airways: No need to register to get double miles. You can find more info about this partnership here.
Cathay Pacific: You need to register for this promotion to get double Asiamiles. You can do it here.
Finnair: No information about the Airberlin offer on Finnair.com. There is only generic webpage dedicated to Airberlin that you can access here.
Iberia: No registration required. You can find more information here.
Japan Airlines: Registration is required. You can do it here.
LAN: Unfortunately there is no information available. Airberlin’s logo is visible on the Oneworld section, but then entirely missing on the earning of miles side that you can access here.
Qantas: Registration is required. You can do it here.
Royal Jordanian: No info about Airberlin found.
S7 (Siberian Airlines): Page dedicated to Airberlin, but no info about double miles offer.
