Did you actually check my posts? Doesn't seem like you read them? There are various issues reported "flying around" in this thread, so fair enough if it gets confusing.

The issue for SQ is not availability, of course it has it usual limitations like no longhaul Biz or First as you correctly mentioned, but that was always the case. The issue is that the flights that one can find, e.g. shorthaul intra Asia Biz or even Eco seem like they cannot be booked at the moment.

For starters, from my trials, SmartSearch usually doesn't pull up much (if any) SQ availability, but that can be fixed by using carrier specific search. Then one selects the flights one wants, selects the passengers + provides emergency contact info, selects all miles and tries to move to the payment screen and ... voila ... Error E2.1xxxxx comes up. Back to square one. I tried probably 30+ flights and combos of all Biz, Eco, Eco/ Biz or even First (CGK has F available at times) and all the same result, error E2.1.

Now again, before you jump into action, I'm not claiming this will happen for every SQ flight / itinerary out there that one may be able to pull up on LM, but as shared, I tried a fair range of locations (all intra Asia) with different cabin choices around 4-5 months out and couldn't get one to actually go to the payment page or at least generate a PNR reference that one could use to call in and make payment for.

Are we on the same page now?
