I'm flying SIN-LHR tomorrow on SQ (in Y, as usual). I pulled up availability on FlightStats, to see how full it'll be, and it came up as wide open in Y. So I thought I'd see how that translates on the SQ website if I try to book the same flight, expecting them to be selling seats for cheap. A return (with flexible return date) is still S$2600 in Y, and a single is S$1600! Why on earth would they do this? Trouble is, this crazy pricing is what makes it unfeasible to fly SQ with the family, especially when QR/EY/EK are offering a return for S$1600. Am I missing something?
