You can now transfer UR points to Avios with a 30% bonus, including British Airways, Aer Lingus, and Iberia. That means the transfer ratio becomes 1:1.3. This promotion runs through September 26. However, BA recently quietly devalued its program, increasing the number of points required for short-haul economy redemptions, which works out to roughly a 20% drop in value. We recommend transferring only when you have an immediate use in mind. After all, UR transfers to BA are usually instant, so there is no need to stockpile BA miles just for this promotion.
