A total of 90 A380's in service, wow!! Where will they fly them to? There will be a lot of airports worldwide that will need to spend money upgrading their facilitits in order to handle these aircraft.
I guess by the time they are in service then most of the B777's will have been replaced. Are EK working towards a true Airbus only fleet? Time will tell.
Good luck to them , I hope they can be crewed, recruitment will have their work cut out for the forseeable future.
