I have booked on SQ for my trip in March 2010 KUL-SIN-AMS-LHR in busuness class on SQ(777-200ER) to AMs but from AMS to LHR its on BD economy. Will I be able to use the lounge in AMS for the 3 hour changeover? The booking says for BD food and drinks can be purchased on board? Will I be in flexible economy? or just economy no frills?
