You didn't get it. Even with same flight on SQ, YQ is a lot less using UA miles compared with SQ. Same level of comfort on SQ. Plus UA miles are a lot more flexible with stopover and open jaw.
Actually I do. UA does not incur YQ indeed, but like what Suleyman says, be prepared to fly non-SQ flights. In fact, be prepared to fly primarily UA flights.
But let me add on something. Its not SQ that isn't playing ball. In fact, I'm damn pissed off about SQ opening inventories to partner airlines without opening Savers to KrisFlyer. It is just United being an Asshole. UA has been, and will continue to be an A*hole airline.
SQ was opened up sometime last year, and people had a field day redeeming on SQ, and gloating about SQ's KF members paying YQ. What they forgot that UA has a famous Starnet block which lasted until only recently, so is anyone supposed to be surprised that UA refuses to give its FFP members access to SQ inventory now?
Is UA all bad? Not really if you put into the perspective that mainland US flyers have limited choice within USA. But I think no one would hesitate to agree that UA, or ANY American & most European Airline for that matter, are rubbish compared to the comforts we are used to on Asian based Airlines.
And now to my favorite topic. SQ's YQ is bloody expensive. All other airlines are much cheaper!!! REALLY??
Let's take SIN - CDG on Business Class as an example;
YQ Prices
SQ = $715.7
Thai Airways - $989.0 - SQ Lower
AirFrance = $925.10 - SQ Lower
Emirates = $1056.90 - SQ Lower
British Airways = $1061 - SQ Lower
Qatar = $644.50 - SQ Higher
Cathay = $576.90 - SQ Higher
And this is just 1 simple search. SQ is never really cheap, in fact they are pretty high up on the pricing game. But to just wack them to say that their YQ is unreasonable isn't fair to them. Everyone else is doing the same.
