If you have a Chase Ultimate Rewards account, you can transfer points to participating frequent travel programs. One program you can transfer points to is Avios which is the loyalty currency of British Airways Executive Club. Usually one Ultimate Rewards point equals one Avios. So 1,000 Chase Ultimate Rewards points will yield 1,000 Avios points.
However, now through 7/31/2022, you can receive 30% more Avios when you transfer Ultimate Rewards points to the British Airways Avios programs. So during this offer, 1,000 Chase Ultimate Rewards points will yield 1,300 Avios.
If you are trying to accumulate British Airways Avios right now, this may be something you may want to consider taking advantage of.
