Basing Rumours
With the 12 hour rule deleted from the CAD371v2, I think a new JFK base and growth on the YYZ base are likely at some point in the near future. CH will soon be able to integrate Middle East patterns into ULH from JFK and YYZ. This will cure the current rostering inefficiencies for YYZ (and a prospective JFK base as well). If ORD service is successful, I would not be surprised to see a 777 base there someday as well.
Rumour has it that the 888/9 service may soon operate to MIA or DFW (both AA hubs) from YVR instead of JFK (since there will be 3 daily nonstops HKG-JFK). This would further support basings in JFK as many YVR CNs operate through JFK now.
Keep in mind that bases will have to open up eventually. Not only do they save the company money when they are rostered efficiently, but the new round of icadets are going to leave in droves once they figure out they cannot live in HKG without housing. The only way to keep them will be through basing opportunities. That is not a problem at present in Oz (for FOs), but NA and Europe have been locked up for a while now.
