Hi,

I'd appreciate some guidance with eupgrades - I booked some previously and it was pretty straightforward finding upgrade space in April from the UK-YVR, but now I'm looking for R space in June, July and Sept and finding nothing. I appreciate its entirely up to AC if they add space, but is there any way to get at least an indication if a latitude fare eupgrade will have a good chance of clearing? I'd be looking at flying from either the UK or Ireland to YVR or YYC, in early September. Is there another booking class that might suggest R space opening up?

Thanks for any help!
