Thank you ELITEGOLDTRAVELLER for your always informative advice.
I was looking at 16 March ex ATH and as of last night the flight was wide open. Then when I looked again today it was zeroed out in all classes and Emirates Reservations confirmed cancellation. Seems as though they have almost given up on operating this flight for the remainder of its life to 25 March.
It noe seems that it has been revised to a Tues/Fri only operation in March but from what you say this is still suspect.
Will get to ATH early enough to switch onto EK106. Pity they do not operate the A345 on the EK106 instead of the A332.
