Transferring Avios from BA to Aer Lingus – any recent success?

[lordy]

Morning,

I’ve been trying to transfer my Avios from British Airways to Aer Lingus via the “Combine My Avios” feature, but keep running into frustrating issues. I’ve gotten errors like:

“Combine my Avios is not available at the moment. Please try again later.”

I already made sure to disable “Prevent cross-site tracking” in Safari, which they suggest might help but no luck.

Tried a workaround by moving Avios from BA to Iberia first, but also having an error doing this.

Booking the exact same flight via Aer Lingus costs around £40 in fees, whereas BA wants £200+ for the same route / plane using Avios.

Just wondering:
Has anyone managed to do this transfer recently (BA → Aer Lingus), and if so, how?

Any workarounds or tips would be really appreciated!

Thanks in advance
