American Express Membership Rewards Points are one of my favourite types of points/miles – largely due to their flexibility. Being able to transfer to a wide range of different hotel and airline partners is great, but knowing how long each of those transfers actually takes in practice is also important, particularly for booking airline award space that can get snapped up very quickly. I’ve therefore been running some experiments to see what the transfer times to Amex’s various partners really are. First up is BA Avios, so if you’re wondering how long it takes to transfer American Express Membership Rewards Points to British Airways Avios, you’ve come to the right place!

How long does it take to transfer American Express Membership Rewards Points to British Airways Avios?

The official line on the Amex site states an “estimated transfer time” of 3 working days.

To get a range of real data points, I made a number of transfers on different days of the week. I found that transfers made during office hours Monday-Thursday took between 24-36 hours.

Transfers made Friday-Sunday generally took longer, but were all still completed within 48 hours.

It’s important to note that these results are currently based on a relatively small number of data points. Please share your own transfer times (including the day/time you made the transfer) in the comments and I will use the info to produce a more reliable average and range.

If you want to know what other types of points/miles also transfer to BA Avios, Ian recently put together an excellent list of BA’s other transfer partners, which you can check out here.
