Looks like Arik is looking for A330 crews. Will that be to replace Hifly pilots or just to supplement them?
Hifly operates the A340, not the A330. Yes, Arik is recruiting on every airplane. See above comments pertaining to 1/3 of the pilot workforce quitting in 2010.
The A330 just got a new fleet manager, who has stated that he will not work with the former acting fleet manager with 5 stripes. Doesn't want him in the fleet at all.
Arik is scheduled to receive a second A330 this fall, and 2 more in 2011/2012. It would be anybody's guess where they might go, how they'll keep crews for it (at the current pay). Or if they'll even show up.
Like most things Arik, it's as irrational as anything else. Five B777 and some B787's are officially on order, also. Since Arik has already been offered the 777's, and turned them down, I'll just speculate that they'll never show up.
