British Airways has relaunched its triple Avios promotion, valid for flights taken by the end of March.

The original offer ran until December 11, but while BA has yet to officially promote the extension, this page now shows it is valid for flights booked and flown until March 31.

BA Executive Club members must pre-register for the promotion here, which is valid for four return trips (or eight sectors).

It’s not clear whether members who pre-registered for the original offer will automatically be eligible for the new validity dates, so to be sure the advice is to register again.

Members will earn triple Avios on all flights in all cabins, as well as on flights taken between Europe and North America with partners American Airlines, Finnair and Iberia.

Triple Avios will be awarded before any cabin or tier bonuses, on all tickets except reward flights, and cannot be used in conjunction with any other offers (for instance inclusive BA holidays, or bookings made using shareholder vouchers).

As an example of how many Avios a member could earn during the promotional period, the carrier says that a World Traveller return ticket in K,L,M,N,S or V class from London Heathrow to Los Angeles, will earn 16,326 Avios instead of the normal 5,442.
