One development I sort of like is the ability (perhaps new, perhaps not, I'm not sure) to check *schedules* to and from cities SQ doesn't serve itself but are served by interline carriers. For example, you can check schedules from Atlanta to Singapore, and SQ doesn't even codeshare to Atlanta. It lists a wide range of options, such as DL flights connecting to EWR, SFO, or LAX, KE flights ATL-ICN connecting to SQ ICN-SIN, or even KL flights ATL-AMS connecting to SQ AMS-SIN. That's cool.

But what you still can't do is actually book the tickets. For booking, you've got to originate and terminate in an SQ city. Although the website does give some interline options (e.g., a ticket from Asia to SFO might give you the option of SQ as far as LAX and UA up to SFO) the ability to start from or end in non-SQ via interlines still isn't there. Hopefully it will be available soon.
