Hi, after a bit of advice and math checking if anyone is willing to assist. I'm one of the many disgruntled BA Gold's looking to jump ship after the changes made to the Exec Club and am very much considering SQ KrisFlyer, and believe I can get Gold with my current travel pattern, but am getting confused between KrisFlyer Miles and Elite Miles.

Currently I do two trips from London to Singapore a year, one with an extension onward to Melbourne, and four London to New York trips, all in business.

Switching to SQ, and assuming flying in Business Standard, the miles calculator says 2 x LHR-SIN returns should generate 33,808 miles, and the MEL-SIN return 9,308 miles for a total of 43,116 miles

Is this KrsFlyer miles, Elite miles, or both?

For the London to New York trips I can switch to United, and 4 x LHR-EWR return is 27,648 base miles - and according to the redemption chart I get 100% or 125% depending on the fare class in business - so worst case is I'll get 27,648 elite miles to combine with the 43,116 from the trips on SQ from above? Where I'm confused is the online calculator saying each LHR-EWR return generates 8,644 miles in business - but is that only if it were an SQ codeshare?

Is this all correct?

Thank you in advance for any help
