We haven't flown Singapore Airlines for about 12 months now but what a difference it was.
Our return flight from Singapore was on an old 777 with TV screens that you couldn't even watch. The good side was that there was plenty of leg room. Service on this flight just seemed to be lacking. I had my blanket over my head and had just got to sleep when I was woken up asking if I would like a meal. When it came to breakfast they looked the other way and I was missed. Not that I wanted the breakfast. It has been the same for over ten years. Three slices of melon , a bread roll and a banana muffin. Also check your pillow they give you. Mine had what looked to be like dried mucus on it. Asked for another but never got one.
Drink service now is almost a non event. A small half cup of soft drink . Except if you are the people in front of you who continually ordered vodka and lemonade and were always given it. No peanuts. I will always bring my own drinks and snacks now.
Singapore to Bangkok flights are always much better. Friendlier crew and huge meals.
They are still my preferred airline and I will still fly them over Thai Airways.
