Economy is economy. Get what you pay for but if you want a bit of comfort on a red-eye flight then upgrade for a better than experience.

Fly to Bangkok or Kuala Lumpur then to Melbourne/ Sydney. Having a bit longer to sleep makes a huge difference. Changi has a great airport though for quick boarding. But maybe avoid Qantas

Be careful about buying duty free out of London if you’re transiting through Singapore, as you may not get it back through security screening onto your new aircraft.

Make sure your hand carry has wheels so they can be drag on and off the flight easier as the flight is nine hour long.

Bear in mind you have to go through security just before you board so give yourself plenty of time get to the gate early.

We have no choice in Darwin, you either pay the money for Singapore Airlines or fly backwards minimum 4hrs to the east coast to catch a flight from there. Ironically fly back over Darwin again. Jetstar used to run a service to Singapore but I wouldn’t recommend them to tie my shoes. My recommendations are. Dress light as the aircon is never cool enough. Wear flip flops as it will be even hotter at Darwin. Declare all your stuff, unlike some airports the Darwin customs people are very nice and polite.

Bring your own food. The food choices onboard, even though one has to pay for everything, including a bottle of water, are very poorly prepared.

a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

It was very good experience on board to Sydney with SQ.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

Once again the meal served was delicious - we got chicken rice

Transfer within the same terminal and lots of facilities at the airport.

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later
