Oscar you don't understand the way EK recruitment works. There are no options, they tell you which fleet you are going on and you take it or leave it (hot tip- if it is the A330, leave it). They do hire directly onto the A380 if you meet minimum Airbus experience requirements. Recently they have had trouble finding people who are that experienced so have been hiring onto the A330 and moving people across. They hate doing that as it costs them more money but at least it respects seniority a little.
