I don't think it will be as simple as just hiring DECs. With the reputation EK has acquired I can't imagine anybody with the required experience wanting to come. Would they hire DECs with less experience than they demand from their own F/Os for upgrade? You now need thousands of hours on an Emirates type to get to the left hand seat. No more hiring DECs who have only flown 737s in Europe as they did last time- and this is definitely a hole they have dug for themselves!
