No frills airline with minimal leg room and no entertainment

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

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

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

Leg room and flight sound insulation is very bad. They broke 3 of my bags with bad handling

I was very impressed with this airline. The flight was comfortable the plane was clean and the attendants were very nice. The zipper on my suitcase broke after I checked it. The airline wrapped it in plastic wrap, so it wouldn’t continue to fall apart. Every item I had in the suitcase was there when I got to Los Angeles. That is above and beyond!

Old flight not worth in economy. Even food was terrible

The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

The seating is spaced out nicely, The crew could have offer more drinks.

First time and very memorable, the finest flying experience ive ever had

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

A very disappointing flight on this Emirates business class. Staff were not efficient and service was not the e usual Emirates experience. Good was particularly bad with very dry chicken and drinks that I had to press call button before getting a drink as my food sat and continue to get cold.

I have a very good experience flighting with emirates. All my expectations were fit well.

very nice experience…….we had a comfortable fly with emirates…this is 6 th time flying with emirates….i recommend friends to fly with emirates…….

This airline is one of the best Ihave travel around the world well use them again in the future the food was higher quality plus your personal aboard communicated in many languages on our flights 13 this was amazing 👏 🤩 😀 👌 😄 thank you

I upgraded to first which was great and overall was a good experience. However, the service was a slight let down this time compared to what I would have expected from Emirates First. I ordered my meals and made a point to order the wine I wanted to have with the main course. The main course somehow came before my starter and I decided not to make a fuss of it and just asked for the wine so that I can enjoy it with the steak. It took quite a few minutes before the wrong wine came which I pointed out. At this point I decided to start eating as medium rare steak (the way I like it) was going to get cold . Few minutes later, a different crew came with the same incorrect wine and I had to send it back and waited another few minutes. Both crew came together few minutes later finally with the correct wine. By then I was more than half way through my steak which is rather unfortunate because the steak was good and and wine was good. Would have been perfect to enjoy them together . They were apologetic and when I mentioned that she had forgotten about my starter, she apologised and insisted that she will make it for me even if it’s just to try. They were nice about it all but so many mistakes for a rare experience in First was disappointing and this flight was paid for not miles redemption, even the upgrade.
