Thanks for the suggestion. Checked EWR to SIN and couldn't find a fare less than $7900. Also that flight is only 9529 miles and I would get 125% EQM. Using the US codeshare with connection gives me 11000 miles with 150% EQM. That's 33000 vs. 24000 miles by my calculation.

It almost looks like the codeshare disappeared from the computer. Oh well. I'll call US, but the CSRs are usually the last to be informed of changes.
