People have said they can't see any AC or TG but I can see plenty of availability on both. I guess it just depends on dates. I also saw some SQ first class availability, which is said to be quite rare (SIN-HLP, not exactly long haul but...).

One good things is that the system also shows 2-stop options automatically. Although these cost more points and I wouldn't want to book them, it's a good way of learning what other routes are available. For example, I was looking at FCO-BKK with Thai and it showed that they have availability BRU-BKK (with connection) on my dates. Since I'm positioning anyway, that was another option I hadn't thought about.

One thing that surprised me was that inter-Asian routes show up availability with much longer routings than expected. I've seen comments here that these routings would be over the MPM, but they do seem available. For example HAN-HKG (527 miles direct) is available on OZ and/or ET/AI via ICN (2952 miles) for the standard 21k miles in C class. Also I found SIN-ICN-MNL with SQ/OZ (4483 miles vs 1474 miles direct) or SIN-PEK-MNL (4561 miles with CA) for the normal 21k miles. There seem to be many of these long routings available with CA, BR, OZ and NH in particular.
