My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

1) crackly headphone jack 2) one of the emergency seats recline. Usually second row does. But in this case neither did 3) food was scrambled eggs or fruit. 4) fruit should not be the option to eggs 5)miserable unpleasant crew not a smile. Thought that was a virgin thing

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

The staff we fantastic and seemed to work very well with each other

Business lounge in Melbourne mediocre. Look at Emirates or Qatar, Qantas! Great friendly crew. Food was good but Emirates is a level above. Business seat good. But can’t compare to Qatar. Main reason for booking Qantas is loyalty and terrific connection via Perth to LHR.

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

TVs didn’t work, air conditioning didn’t work, flight crew came by one and that was it

It was delayed and no.entertainment unit. Lion group air is giant company with poor record of service.

Boarding was generally quick, staff were friendly and did assist people when needed. The plane wasn't cleaned well with remnants of the last passengers. Tray tables were falling down and back of seats falling apart. The AC was turned up too high and we were all freezing, i was actually shaking uncontrollably until the heating was put back on. No entertainment at all which is hard when travelling with children. Minimal food choices and cash only option. I know its a budget airline but some minor improvements could make a good difference.

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

The FA told me that the dinner was vegetable curry which turned out to be vegetarian (tofu) which I don’t care for but that was the only disappointing part of my trip.

Updates from pilots about delays would make them less frustrating.

Almost 3 hour delay. First because the crew was late. Then a technical problem with the airplane.

Connecting British Airways flight was 29 hours delayed so I never made it on this plane

It was truly amazing. I will do it again! Excellent!

My suitcase did not arrive . I had to change my flight to the US . I was also without all of my stuff that I had to pay through my teeth for my suitcase . I am still miserable from all the stress BA had put me and my family and friends through

Truly felt "taken care of". Will definitely fly British Airways again.

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.
