Booking Iberia at T-360

[as02]

Hi All!
I’m looking to use my 2-4-1 voucher to outbound on Iberia at T-360 days. Is it possible to do it via the BA call centre or does one need to transfer Avios to Iberia to book online?
What’s the best time to call BA?
Thanks!

You can only book using an BA Amex 241 on BA so you will need to call – I’d suggest you start doing this as 365 days, which is when routes become available via the IB App and then ring daily going forward.

There is no set time when IB availability is released to BA
