I booked a ticket on the EK site and it warned me that I can only upgrade at check-in. However, neither the fare rules nor e-ticket document state that it is only available for upgrade at check in.

On MMB, it lets me select the "upgrade by miles" tab but it states that none of my sectors have availability (while according to EF all four do.) Is it showing all 4 as unavailable because my ticket only permits upgrades at check-in?


Does EK no longer write that the ticket can only be upgraded at check-in in the comments section of the e-ticket / in the fare rules?

I am not frustrated and am perfectly happy waiting till check-in to try and upgrade but just want to know if the issue is that EF is wrong, the EK site is buggy or my ticket doesn't allow upgrades.
