A friend has managed to book an 'I' seat on the above flights via the BD FF scheme.


I had intended to use the same flights but book in 'B' and upgrade. Even at this stage months away, there is no 'R' availability. In addition, no 'Z' class on AC859!
I know its my choice for travelling on the same flights, either book in Latitude 'B' and 'wait and see' or 'bite the bullet' and purchase in 'D' for AC859 and 'Z' for AC856.
From other posts, I see its all down to yield management. - Would I be correct in saying that it is 'likely' that AC will release additional 'R' or indeed 'Z' at a later date?
