Update: This promo ends today!
Eligible hotels include:
The only hotel chain with a worthwhile transfer ratio is Marriott at 60K:25K. With this promo 60K Marriott would become 32,500 Avios.
Avios aren’t what they used to be when short-hauls in the US were just 4.5K miles and AA had amazing availability, so only transfer if you have a short-term need for them.
Bonus Avios can take 4-6 weeks to show on your account from the date of conversion.
