According to this it looks like codeshares are no good for IB
Eligible flights are defined as those flights marketed or operated by British Airways and those flights marketed and operated by Iberia.
- 'Marketed' means the flight will have a BA flight number (in your itinerary or on your ticket).
- 'Operated' means the aircraft that you travel on is a British Airways aircraft (including franchises and BACityflyer).
- 'Marketed and operated by Iberia' means the flight will have an IB flight number and the aircraft you travel on is an Iberia aircraft (including franchises).
Its not a real issue for me as I don’t travel on IB a lot and BA have some good codeshare options in Australia that should do the job.
Regarding Mrs Jase, should I sign her up or just add her to my Household Account?
She doesn’t fly as much Dom as me so being able to still earn TP’s whilst pooling the Avios seems a good option
