The 762ER has a 6,600nm maximum range so she could do DEN
, in theory (winds in one direction might hurt that, though).
And the 763ER has a 6,105nm maximum range, so she could do SEA
, for example.
However, in three class config they're a little light on passenger load, and airlines like UA
use the 777s to tool around Asia between runs to and from the US.
offered around-the-world service in 1995, a 763ER did at least the DEL-LHR
portion. She could have done HKG
, as well. They'd only have needed the 744 for LAX
