My only criticism is that the flight attendants didn’t pass through the cabin with water during the 9 hour flight.

The service from the Singapore Airlines is always impeccable. The food is delicious. The business class seat is spacious and wider than all the US airlines. There are plenty storage space in your seat space. The entertainment system has many choices and has a lot new release movies and shows.

Unfortunately, the ride on Boeing 777 is not as smooth as the Airbus'. The noise in the cabin is louder. The seat is comfortable but the bed is not. First, the flat bed is not transformed by a button and it needs a physical person to flip it over. The mat is thin and I can feel some hard edges while lying down. The noise from the engine transmits to the bed and it is hard to sleep even with the noise cancellation headphone.

That the A380 was only 70%full, resulting in me getting three seats to myself. I was able to stretch out and sleep for most of the flight. Food and service were top notch. Better value than Lufthansa or American, for the overall flight experience. You could fly cheaper, but not better, in economy.

Though we landed early at JFK, we had a one hour wait on the tarmac until one of the only two gates capable of receiving an A380 opened up.

My flight was delayed by 2 hours so I missed my connecting flight in Singapore. There was a huge queue of people who missed their connecting flight cos of an accident in the runway. The airline did nothing to prepare for this situation. It took hours to get another flight organised, communication was non existent and refreshments took ages to come. Airline didn't help with finding a hotel for stranded passengers.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
