Avios Part-Pay on the Phone
Does anyone know if you can Avios part-pay on the phone?
I want to do MAD in CE with the £100 reduction for 7500 Avios, however I'd like to get on the Iberia flight with the A330, but I think for that to be possible (if it is possible) I'd need to be on the BA codeshare flight number, which I can't do online.
Hopefully that made sense...
