While de 777s are expected in march 2 to be exact.
If Arik is to get the planes that are currently on the production line in Renton, they won't be airworthy on March 2.... to be exact ;-) Boeing says third quarter 2010, which probably will be 2011, per Arik's own public data.
Also, I think your other projections are a bit optimistic. No mention of A330's on the Arik public web site, and no press release to such. Perhaps you know of a link to such machines?
The route map is on the Arik web site, included future planned destinations. No need to guess. They want you to know!!
As to how the loads are to JFK, or any place else out of Lagos, just get your cheap aviation frequency scanner, and listen to what the crews tell ATC on the radio, every time they take off or land. Simple, cheap way to judge your competition!!! Maybe there should be one of these:
