Yes, however only one stopover.
Forgive my ignorance, when you say one stopover, for this this route: syd-bkk-nrt-sin-syd
I can only do, SYD-BKK, call BKK my destination (stay a week), then fly out to tokyo and stop here for a week and then fly from tokyo to singapore (can't stop here ? i.e. can only transit through and catch my sq flight to syd straight) ?
Cheers,
K.
