Indeed - but the most limiting factor is it only shows nonstops, not same plane service. AC33 YVR-HNL-SYD for example does not come up in either YVR-SYD direct search or YVR-All Airports search. The same applies to all the SQ flights from U.S. west coast via an intermediate point in the Far East en-route to SIN as another example.
Am not sure why the Star TT programmers don't load same plane service in the searches.
Seasonal services do appear provided that a) the carrier has loaded the flights into the CRS's, and, b) your date range search includes the seasonal dates applicable.
