-Guam-Hong Kong with the 747SP.
Guam is under going a considerable expansion in military construction and population.
The US and Japan recently agreed to move 8,000 Marines from Okinawa to Guam, when you include dependents and civilian contract support workers Guam is looking at an additional 15,000-20,000 new residents from this move alone. Plus all the construction workers needed to build facilities for these new tenants.
The Navy is basing 4 Los Angeles class attack submarines in Guam, they are planning to base more Subs and possibly surface ships in Guam. It has even been discussed moving a Carrier from the West Coast to Guam. All of this means again more Sailors and their dependents and civilian contract support workers moving to Guam, plus additional construction contractor activities.
The Air Force is also expanding Anderson AFB, they now have a permanent Wing assigned to Anderson that supports rotating Squadrons of B-1s, B-2s, B-52s, KC
-135s and soon F-22s. Anderson is going to see growth not seen since the Line Backer II
days of Vietnam. Again additional airman and their dependents, as well as Government contractors.
Safe to say the population and Government activity on Guam is growing substantially over the next decade, a scheduled nonstop to the Continental US as well as additional capacity to Honolulu will be needed.
