I was trying to get a return flight to Singapore for two during April/Mai next year.

As usual; nothing available on Singapore Airlines in Business....

...but I seem to be able to get Thai Airways - and I I go through Frankfurt I get their A380 and First Class seating.

Have anyone tried it ? Is it worth the added connection to Frankfurt ?
Also - it is fairly high cost of fuel/tax surcharge (~5000 NOK per pax), it seems that "fuel surcharge" is added when booking StarAlliance awards, but on SAS there is tax only.
