Inklet I Agree but as delivery is from 2013 onwards and they would still be flying Boeings until 2018/9 then I would reckon that would work its way through the system pretty quickly.
I also think that Airbus would provide a lot of support to ensure training was available but even if not are there many pilots now with FR who would seriously be there in 6 years time when the bulk will have arrived. Listening to some people the answer is clearly NO.
Never rule anything out as some of the Govts involved in Airbus may want to make big concessions in other ways to FR to gain that level of business.
Interesting whether is a 800 or 900 series they would look at if they went Boeing given 215 seats on a 900 series.
