Finnair is offering Finnair Plus members double miles between now and February 28, 2011.
They must fly with Finnair or other oneworld partners to accumulate double award and tier points. The offer also applies to codehsare flights.
The double points will provide enough points for them to upgrade from Basic to Silver level when flying on any round-trip long-haul route in business class, which requires 40,000 tier points. Under normal circumstances, these 40,000 points can only be accumulated when taking 24 flights during the basic tracking period.
Finnair Plus Silver, Gold and Platinum members enjoy express business class check-in facilities, Finnair lounge access and extra baggage allowance.
Non-members can start earning double points immediately upon joining here.
