Mediocre 3.0

Pros: The plane was new. The in flight entertainment system was good, although I never got to experience it fully because the Flight attendant kept switching it off, as I had paid extra (an arm and a leg) for a “bulkhead seat”

Cons: The service was beyond awful! The Flight Attendants had a “could care less” attitude. I had special ordered a meal, and they gave me the wrong one. I did not want to make a big deal, so I just ate it. Then they did not offer any beverages when the meal came! I literally had to beg them to make me their famous “Singapore sling”. Shocking really!!. When I had my coffee, my request for cream and sugar went ignored THREE times. Finally they grudgingly gave me only cream, rendering my coffee undrinkable. .....And the list goes on. Never ever will I travel on this horrid airline again!

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,
