Hi again,
you're skywards Gold so must know the seating configs better than me who's only flown EK biz class once(4 legs) and econ a few times.If it were me I'd select the best seat I could from what's available now then try phoning EK or when OLCI opens Thursday hope a better seat is open with last resort get to the airport early.
Don't Skywards gold have any clout when it comes to bagging seats,I know BA golds do!
