Hello all,

For the first time in 5 years I have been sent a proactive upgrade for £450 from Y to J on EK018 MAN-DXB on the 9th Dec. Does this indicate that Y is oversold and is anyone able to see if that is the case? If i purchase the offer and J is oversold will i be offloaded first and have ended up paying EK more to still end up stranded? The email states that chauffeur drive is unavailable so i would have little extra time in my plans to enjoy the lounge.
Is it worth buying or just turn up and see if i get upgraded? And experience or comments welcome. Thanks in advance.

P.S. This is the return leg of my trip if that makes a difference.
