Neither flight had Saver availability when I checked the website, but there was no pushback to changing the booking (TBH - I was expecting they would ask me to top up to an Advantage award, try to charge a change fee etc.).
I also got the sense that they could've rebooked us on a partner ex-IAH if it was just 1 J seat, but couldn't do it for 4. So rebooking had to be on SQ metal via one of their US gateways.

We really enjoyed the easy access to SIN from IAH, and are very sad to see the end of this flight.
