HKG-SIN December 2014
I was GO, Brother was SL, Parents were GR. We checked-in together under the same PNR.
Check-in agent offered op-up (Y to PEY) to me only due to overbooking and asked whether I would take it.
On board the aircraft, PEY was rather empty with maybe at least 5+ seats around me. Parents reported Y to be full.
