Good 7.0

Pros: Fast boarding. Early arrival. Comfortable seat.

Cons: I had to ask 3 times for an arrival card from the crew. Bread was dry. There should have been a breakfast served prior to landing, but no food service after 1 a.m. though flight arrived at 7:40 a.m. Timing of meals was not convenient for me at all. They wake you up at 1 a.m. for your main dinner. I would have preferred to sleep until 5 a.m. then have a good breakfast. The amenity kit in Business Class was substandard when compared to other airlines

Pros: I liked that on the longest leg of my trip - I had an entire row to myself to stretch out. Im old, things like that are important...along with compression socks...haha!

Cons: I think the food - I dont know exactly what, because we're on a plane - but I think it could be a bit more appealing? More greens, colors? Not sure, but it was okay.

Excellent 9.3

Pros: I loved that the airline offered several meals, snack options and drinks. The attendants were amazing and would highly recommend Singapore airlines to anyone flying internationally

Cons: The limited arm room/personal space. Not much leg room in economy for a 10 hour flight. Would be nice if airlines would decrease the number of seats and give a little more room so people aren’t hitting each other in the head with their arms

SIN
SEA
Excellent 9.6

Pros: The crew was very polite and very helpful. Boarding process was smooth and easy, however, the Singapore airport has security checks at every gate prior to boarding. This meant that after clearing this security process at the gate, bathrooms were not available until after boarding the flight and drinking water stations were not easily found in the secure boarding area. The aircraft was comfortable, menus were distributed early so that meal options could be made with full information in advance. The food was good and made available at routine intervals.

Cons: On a 14 hour flight, staying well hydrated is very critical and difficult. It would have been nice for the crew to make more frequent trips through the cabin to offer just water refills to keep passengers hydrated and reduce plastic cup usage.

Cons: A comfort kit on a ultra long haul flight goes a long way

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

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.
