Singapore Airlines KrisFlyer - *Alliance Upgrades

I tried searching, but i could just be a idiot.

Is there a way for me to see which if any fares/dates on Singapore airlines are available for as *Alliance upgrade? Specifically for the JFK-SIN route.

Thanks.

No. You'd hv to check with UA if you plan in using their miles for upgrade. Only certain fares from economy to Business qualify. Those booked in S or E class I think. No Business fares to Suites upgrade allowed.

Aren't the codes Y,B, and S for SQ and D and C and Z iff the plane has a normal F and not suites?

Yes, you're correct.

UA miles are good for upgrades to First from C, D, J, and Z business fare classes on SQ. Upgrades are possible from B, S, and Y economy fare classes to Business. UA *A Upgrade Awards (http://www.united.com/web/en-US/content/mileageplus/awards/upgrade/saua.aspx)
Well once the UA system is up and running again. :rolleyes:

Fare classes for other *A programs may differ.

UA does not have restrictions when upgrading on SQ using the star alliance upgrade awards??

AC has aircraft restrictions which makes me so mad!!!!! it just blows

"Singapore Airlines (SQ) excludes A380 / B773ER / A345 aircraft" which pretty much means every single flight from NA :(
