Most food was non-vegetarian only. Was tricky to get vegetarian food. But the flight staff have us their own vegetarian lunch. Which was way more than I expected of them, but would have preferred of the flight just had that as an option.

They would not accomidate a flight change after I was delayed in an accident getting to the airport. One desk said there was a seat on the earlier flight and sent me out of the gate area to the front of the airport. When I got there a few minutes later they said no there is no seat. I was upset because I had to wait 6 hours now and go back through security again. I asked to speak to a supervisor. They pertended not to understand. I was persistant and then they siad oh here is a seat on the 1:00 flight. Then he goes do you want window or aisle. If there was no seats whey do I have a choice?

Toilets were kept clean through out the flight. New and clean airplane. Good space between the seats.

Flight attendant was rude in general (serving food, drinks, answering questions), he skipped rows when giving hot towels (I wasn't served a hot towel). In-flight entertainment: limited movie selection, even more limited tv shows selection. Music section was very poor, it needs more selection with variaty, known artists, more radio channels. And music tracks should be in a tracklist form with song information, not only 1 hour-long tracks of back to back music (with no info). Meals - Mains were ok, deserts were terrible in both of my flights. Snacks were also bad, a scone and beef and cheese sandwich. Very blend, white bread only and oily. We weren't served enough bevarages, so oily and high-carb foods made me very thursty. No water fountains, it'd be great to have some around since staff does not give enough beverage and I was forced to chuck my water before boarding the airplane (the water I bought in the airport after passport check!!!!!!!) It was extremely cold.

Some flights have personal movie screens while other flights have communal screens that just show funny cat videos over and over again, then movie trailers. On the longer flights that really gets old. There was an entire section of the plane where no one bought seats because they were too expensive. After take-off people wanted to move into those seats to sleep but the stewardesses said that we would have to pay 1000 CD for the honor to use those seats...these were the same seats that we were in just a bit more in the front of the plane....people were pissed. These were not 1st class seats.... Uncertain if I would use this airline again....

Love that everything is included. Food, drinks and entertainment. The crew were great and nothing was too much trouble.

Boarding of the A380 was ridiculous. We were lined up well ahead of boarding, then moved to another line, then moved again. Once we were lined up we had to stop and start, other people were pushed to the front again and again. This could have been solved by leaving one lane free for people sitting upstairs, or 'preferred' fliers. Instead everyone was pushed back and had to wait. I've never seen an aeroplane boarded so badly and we ended up being some of the last people on the plane. Badly organised and just plain awful.

Prices are per person, are for e–tickets and include all taxes & fees in SGD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an and someone from our team will get back to you promptly.
