I like the polite and friendly air crew. Boarding from the aircrew was fine and orderly, however the Changi gate staff were disorderly and chaotic. I found the economy seating was way too small for a full service airline. It seems about the same size now as the budget carriers and I’m not sure if the value for money is there anymore. The saving grace with that is the generous baggage allowance. Our Singapore Darwin leg was on a 737-800, a small plane for an almost 5 hour journey. As was the case on our Darwin Singapore leg, the flight was full. So it was quite hot and unpleasant for the hour extra we had to wait on the runway before we actually took off. Total time in that cramped seat was close to 6hrs and no way of sleeping even with the fatigue of our 12.5hr Munich Singapore flight preceding it. I love Singapore Airlines and value our sole full service direct connection from Darwin, but we paid a lot of money for the cheap seats and it appears that the airline has slipped since we last flew with them in 2019.
