Our flight to Bali was cancelled due to the volcano eruption. We did not receive any compensation, but Singapore/Silk Airlines told us they were able to get us a flight home to LAX instead, but that it wouldn't be until the next day. We spent money on a hotel and food and waited until the next morning, got to the airport early for check in only to find that Singapore/Silk had in fact, given up our seats that they had promised us. They said that we now would have to wait another day just to get a flight from Singapore to LAX. We asked to speak with a manager, and eventually were able to get two seats due to cancellations. This was intended to be a very special and romantic trip that was essentially ruined. Since no one could have anticipated that the volcano would cause cancellation, we should be refunded for our flights. We are so crushed that we did not get to go to Bali, and now we may NEVER get to go because we are out of money. At the VERY least, the leg of our flights from Singapore to Bali, and Bali to Singapore, should be refunded. We are extremely disappointed.

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.

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???

There were a lot if security checks but the boarding crew was very helpful and let me check in a bag at rhe last minute with duty free shopping items that i would not have been able to carry with me on-board the airplane.

Snacks and candy served we're of low quality. No prayer facilities inside the plane. They didn't allow me to pray though I got some empty spot to do so. They brought the issue of safety. While fasten seat belt sign was on I found people standing, walking, using toilet etc but air Crew did never brought up the issue of safety.

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.

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.
