You're all failing to see the positive....free upgrades (hahaha) on SIN-HKG once the 738 starts
I flew HKG-SIN the other day on the 747. The plane was less than 1/4 full. UA is simply right-sizing the market. SQ can continue to operate A330's and B777's all day and probably have those flights full. But most O/D HKG-SIN traffic won't look to UA, the big American carrier, for seats. Of course, when I was looking at random UA was $199 while the other airlines were over $600.
