They'll just alter the rules to suit what they want and need to do. They've done so in the past and they'll do so in the future.
For those that remember, their stated policy last time was to only recruit those Captains that had 3000 hours on aircraft of the type the EK operated, they then almost immediately gave B737 and A320 rated guys the DEC jobs.
At the end of the day, they'll do what they need to, to ensure they are able to operate the aircraft that they have being delivered, anybody who can't understand that fact is the moron.
