Does anyone have experience in purchasing upgrades from Y flex to J on Emirates (using $ not points) at check in?

Does anyone have experience in purchasing upgrades from Y flex to J on Emirates (using $ not points) at check in? Interested in feedback on availability and cost.

I attempted to do this last week (ie. Y Flex upgrade to J) but was told by the Emirates service desk that paid upgrades are not available for passengers travelling on a Qantas ticket.  :(    Always worth a shot I guess ....

Thanks, I will travelling on an EK ticket so that should not be issue. I attempted to purchase an upgrade via the "Manage a Booking" facility on the Emirates website but as it was booked by a corporate travel agent I am not able to make any changes prior to check in.

It may be worth dropping a line to your corporate travel agent to see whether they could purchase this upgrade for you (with the upgrade cost charged back to your personal credit card). It can't hurt to ask.

Thanks, I will see whether that's an option - it would be interesting at least to check the cost. I thought I might be able to sneak a bargain by purchasing a last minute upgrade at check in, although obviously this carries the risk of the business cabin being sold out.
