The air crew was wonderful when they were around. Unfortunately you are abandoned most of the flight. You find yourself thirsty often during a long flight. It was a free for all if you wanted anything. Get up and go get yourself. You would accumulate trash without anybody coming by to take it from you. The entertainment systems are aging but that’s due to the age of the aircraft. Call me spoiled but once you fly on Singapore Airlines everybody else doesn’t meet the standard.
