I’m just about to fly out of EDI for AKL. I’m in J to DXB courtesy of a discounted miles upgrade from Y. EK448 from DXB to AKL tomorrow (1 Oct) is apparently heavily oversold in Y and J is full - lots of staff on the flight by all accounts (still some seats in F though). I’m Skywards Gold on a FlexPlus Y ticket, should I request an upgrade to J using miles in DXB, or simply sit tight and see if an Op-Up comes my way? All thoughts most welcome....
