The May 26 777 new hire class will be starting OE the third week of July. I would expect the June class to be starting OE the end of August.
The 5th B777 will begin operating in August sometime. The current routing is CVG/ICN/HKG/ANC/CVG. With the addition of the May/June new hires we will be staffed for the 5 B777's.
I'm not sure what the current training timeline is for B737 pilots.
