British Airways has launched a new double Avios promotion, for flights booked and taken before the end of the year.

Executive Club Members must pre-register for the offer here, which is valid “across all routes and cabins”, for up to ten flights.

Note that the promotion is valid on transatlantic flights with a BA prefix operated by joint venture partners American Airlines, Iberia and Finnair, and on domestic flights within the UK and Southern Africa operated by Comair, Sunnair or BA Cityflyer.

But flights included as part of a BA Holidays package will not qualify, nor will any other flights operated by other BA franchises, codeshare partners or Oneworld alliance members.

The bonus will be calculated on the base Avios earned, with cabin and tier bonuses applying as normal.

Members can register for this offer here.
