Thanks!

If you start elsewhere in Europe, only dates in Early March will work because this is about when there are seats in Fare Code A on the LH/LX codeshare operated by SQ between FRA/ZRH and SIN.

CPH is the only comparable starting point in Scandinavia.

Copenhagen (CPH) - FRA-SIN-FRA-CPH
25032 DKK Roundtrip ($3632 USD)
13608 Miles
26.69 cents USD per Mile Flown





Oslo (OSL) - FRA-SIN-FRA-OSL
45469 NOK Roundtrip ($4241 USD)
14184 Miles
29.90 cents USD per Mile Flown





Stockholm (ARN) - FRA-SIN-FRA-ARN
54837 SEK Roundtrip ($5201 USD)
14284 Miles
36.411 cents USD per Mile Flown





There is one single date that works in January from anywhere in Europe, but it's insanely expensive because it uses a Singapore Airlines fare, not a Lufthansa fare. The SQ A fare is still discounted First/Suites, but the base fare is much higher than an LH/LX A fare.
