Don't forget that while an extra stop is no problem in terms of the fare, there are additional taxes to take into account and the additional time of an extra stopover. If you are flying in Y it might be worth paying the surcharge. You get a bit more room with SQ on SQ22 as well, if you can stand 18 hours in a tin can.
