The 737 MAX can fly approx. 500 nm more than the 800's (just for future's sake), to give you guys a perspective, Westjet just started ETOPS operations from eastern Canada to Ireland and UK via the 737, another would be Caribbean Airlines flying Toronto to Port of Spain in about 6hrs, full capacity.
Should be no problem for FZ to fly to Europe but i think they will work closely with EK as to which cities they exploit
