Its being contemplated for Cabin Crew using a portion of the current LHR CC base.
I don't think there will be a need for a CC basing.
Potentially I wouldn't be surprised to see London crew depart LHR about 9 pm, arrive Dubai about 7am next morning, Depart Dubai 2am that night after about a 14 hour slip and be LHR 6am.
Oz crew Arvo departure, arrive dubai midnight, 34 hrs slip depart 10am following day, arrive back in oz 6am next day. S/o's on the same Pattern.
Just my guess.
