If you wouldn't mind sharing the price you're paying, one thought would be to compare it to a 3-continent RTW ticket, that would have allowed some additional segments in North America before or after your departure, and/or a 4-continent ticket that would have allowed visits to Australia, Africa, or South America.

For example, an itinerary like ORD-xLAX-HKG-DEL-HKG-xLHR-IST-xLHR-HEL-JFK-MIA-LAX-ORD would cost around $3900 plus taxes in economy, or $7500 plus taxes in business; a four continent trip like ORD-xLAX-SYD-AKL-HKG-DEL-HKG-LHR-HEL-JFK-MIA-LAX-ORD (which is 12 segments out of a maximum OF 16) would cost $4100 and $8300 in Y and J respectively.
