Cons: - There was a massive line for boarding and it took a while. We ended up leaving a little late because of it. - The crew overlooked the row I was in a few times. We had to call for assistance to get rubbish removed. - One of the toilets didn't have running water in the basin from the second hour of the flight onwards. - The galley in the back was locked for most of the trip. - The food wasn't cooked properly. - Everyone was asked if they wanted a drink with my meal except for me.

Pros: Did not realize I purchased a “no checked bag” fare - and the $60 each way charge really pissed me off, along with the &48 charge to guarantee a window seat again, each way. The site was misleading, and I resent being peneluzed for trying to be efficient. A two week work trip needs to include a checked bag.

Cons: For a new plane, seats are very cramped. If you drop an earpiece on the floor, you pull a muscle to retrieve it / or make. Everyone in your row stand up. Decent movies mean a box under the seat cuts into legroom. A cramped, miserable 7 hours for this 6’0 tall American. Staff was as helpful as they could be, but my knees still hurt.

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

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

We aggregate tons 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 don't guarantee prices we find.

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

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.
