Hey guys,
as my father is planning a trip with EK a question concerning upgrading a ticket with miles came up and I couldn't find any answer yet.

If my father (or anyone else) has a booking with EK, is it possible that I upgrade him with my skywards miles?

E.g. for Lufthansa this feature exists, so that you can be the "sponsor" for an upgrade and upgrade someone else with your frequent flyer miles.
However, I couldn't find anything similar for EK.

So, does anyone of you know if I can upgrade a ticket of someone else with my skywards miles, or is this not possible with EK?

Thanks for your help!
