Can anyone confirm that the multiple pricing options are available to CSRs if I were to make a mixed class Avios booking by phone?

The reason I ask is that I have a J Avios booking that I wanted to add Y connections to, but the CSR was unable to, and cited one of the reasons was that since I had chosen to reduce Avios and add cash and those pricing options were not available to them they couldn't change the booking. I was curious if that was just for booking changes, or new bookings also.

This might determine whether I take a gamble and risk reward inventory not returning if I cancel and rebook over the phone. I know I could do this as a separate booking but one end is quite tight and I would prefer not to have to recheck bags, and the protection of a single booking.

In hindsight I should have called but wasn't aware at the time that mixed class bookings could be made over the phone.

Thanks

 

To answer my own question...

Yes, the multiple pricing options are offered.

And as a data point, within 30 minutes of cancelling the original reward booking, both outbound and inbound inventory was available again (MAD-SDQ-MAD on IB)
