I have had the interesting (!) experience of working for both. We always thought that it was bewildering that flydubai was not set up as an 'Emirates Express'. Whatever you may think about EK the training standard in FZ was jaw droppingly awful / worse and tragically the inevitable happened. You would think that the brand would be irrevocably damaged post - Rostov. There are some good people @ the coalface in FZ and for their sake a take over would be a good thing.
