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.

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.

One crew is rude while I was ordering food while she is delivering the beverage after the order time. She simply told me they don't have what I want to order and leave. After 5 mins, I pushed the service button and nobody responded. After half hour, I ordered the food from another crew passed by. After I landed, they suppose to return my stroller set at the airplane gate. But they said it is not there, ask us to wait at the airport gate. We walked outside and they broadcasted again, I didn't hear very clearly but followed most parents to walk out. We wait at the baggage claim for almost 1 hour and finally, the baggage crew came back to the gate and found our stroller.

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.

Extra leg room in emergency exit row They actually played a movie that was in English. Not the first time I have flown China Southern, but the first time I had air control above. This is something I feel makes flight a bit more comfortable.

Food is terrible. They ran out of wine during first beverage service. Exit row passengers are not permitted to keep items under seat. Flight was delayed at take off and perhaps in route because we were over an hour off of schedule. Aircraft always had a line for the bathroom, two is not enough for amount of people and duration of flight. I do not know if there was bathroom in front, it was sectioned off.

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,
