Yes interesting moves on the chess board currently, mutt.
Two moves I have heard "around the water bubbler" are;
-AAI's days (& other chtrs) are numbered as they wish to bring all Saudia tail operations in house to control the brand better. This will take some time as the numbers evolved are huge, especially with the season soon to begin.
-immediate flow of crew is to 777 growth mostly but the intention is to keep crew "on type" for ease of training in the future. I guess this means watch out for some new Airbus toys, in this new bulk order of aircrafts to come. 787 staying in house for now. 20 to come now, :-)
(PS I am aware of the type crossover asked, when changing to the left seat but there simply may not be available training slots to do this in the future. It's definitely smarter to stay "on type" & and not lose experience gained, definitely more efficient and what most other airlines do... )
