Attentive and polite staff. Comfortable planes. On time flights.

I accidentally left an external battery in my check in bag and they stopped me to open my bag and remove it as I was boarding. This is obviously my fault but I wish they had called me up earlier to not disrupt the other passagers and slow the boarding process.

The business class bed was the best I have yet encountered. The food and service were great. And the stews? Gorgeous and so agreeable. One young lady even helped me with my back injury; turns out she was studying physical therapy. You can't find a better ride than that,

I like the services from Singapore Airlines.

Your web site tried to charge me $90 for aisle seat, do you agree that this is a big joke or what? I have decided no use your company any more. Not sure why a great airlines like Singapore Airlines would partner with your company???

Good 7.3

The people were excellent.

I had planned to check an extra piece of luggage, gifts and purchases for church needs. They wanted to charge me $3,655(!!!) for that. Absurd. I had to leave the suitcase behind. I will probably fly on a different airline whenever I go to Russia now.

Service was nice.

Comparing to recent businesses class flight on Emirates; Singapore airlines seat does not recline to flat bed. Boarded flight st 11pm and arrived at Singapore at 7am. Toiletries like tooth brush and paste, razor etc. were not provided. Emirates provides, so we did not pack in-flight.

The A380 is an amazing plane. The flight was smooth and the engine sounds were fairly low.

Waiting on line to check in was more than a half hour although there were probably only 10 people ahead of me. Got a hard time on the weight of my carry-on being more than 7kg although I had to point out that my ticket allowed me two bags that were 23kg each - I had nothing to check. Eventually, when I pointed out that I could wear enough of the clothes from the carry on, they agreed to let me take it on. On board, the service was cold, bland and infrequent. The entertainment system lost sound perhaps 20 minutes into the flight.

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals 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.

If you have 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.
