Cardholders of all Oneworld member airlines' frequent flyer programmes will receive double mileage points over a two-and-a-half month period when flying with Qatar Airways.
Similarly, members of Qatar’s Privilege Club loyalty programme will receive double Qmiles rewards when flying with the carrier's new Oneworld partners.
The offer marks the entry of Qatar into the alliance. The Doha-based carrier officially joined Oneworld on 30 October 2013.
The deal runs from 15 November 2013 to 31 January 2014, apart from during the Christmas holiday period of 20 December 2013 to 5 January 2014. The offer terminates a week earlier for Cathay Pacific's Marco Polo Club cardholders on 24 January 2014 and those flying with Cathay.
Earlier this month, Qatar brought in changes to its QMiles Privilege Club, including introducing a new Platinum tier. There are now four tier levels - burgundy, silver, gold and platinum.
Privilege Club Platinum and Gold members will from today be able to access 550 airport lounges worldwide offered by Oneworld member airlines when they fly with one of the alliance's carriers.
