Seems like a different wording on the BA website now... Book a Reward Flight in our World Traveller, World Traveller Plus, Club World or First cabins for 50% off the Avios required. Alternatively, if you prefer to stay closer to home, you can book a Reward Flight for 25% fewer Avios in our Euro Traveller or Club Europe cabins. Book before 13 October for travel between 6 October 2020 and 30 June 2021.
