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

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

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

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

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

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

Not that good The crew in the plane were rim professional & almost lost in their work distribution

Food is really bad, not to the Emirates standards. Coming out of Houston airport is very confusing,

The flight was great. We had to purchase extra long seats for the long flight. But overall it was great.

The crew manager let the staff down by not ensuring special dietary requirements meal were coming in drips . The poor cabin crew did not stop . If organised the cabin could take a short break ..The cabin crew were AWESOME UNLIKE THIER TWO MANAGES!

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

Check-in process at Bengaluru airport was atrociously slow. Emirates should allow baggage drop option after online check-in and verification of documents. The rest of the flight was quite good and we didn't have any complaints.

I enjoyed the live television programming for entertainment, and honestly everything was acceptable. It’s just that I choose emirates, because they have always been so much better in so many ways – food choices, service, accessibility, friendliness of the staff. None of those things were poor, but they have definitely slid from their position of excellence. One example would be that after the dinner meal was served, the flight attendants huddled in the back galley with the curtains closed (by the way, that’s where snacks and drinks are), and you have to interrupt them to go back there to either ask for something or to get a snack. While they do not respond in an unfriendly way, you are led to believe that you are interrupting them by coming to get a snack or making a request. Even something like, “ Yes, how many I help you?” would be a great improvement.

The individual attention the crew gives to passengers is commendable and I find them positively helpful.

Food was not eadable. Testless and not apealing. order for indian vegitarian, recived spice less. combination of main course and side iteams are far away from traditonal food, serve less iteams. , but eadoble. Thanks

Quality and tasty Food and service, bigger seat comfort and leg room, etc.

I had first class service from them. A little late taking off, but no major problem

No towels or tissue and chocolate and mint provided before arrival

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

The staff at the check in lied. I requested aisle seats he said he gave me aisle seats. In actuality he only gave me aisle seat for 2 hour Karachi to Doha flight. From Doha to Dallas flight he gave me middle seat .

Boarding procedures are very tiring. We have to clear security twice for our connecting flights from Doha. Also every time we board flights we have to show boarding passes 5-6 times.

No separate queue for business class/platinum passengers. I had to stay in the long queue to board. I requested breakfast before landing, but the crew didn't offer, except a coffee with milk. No tea with milk was available. Had asked for cookies, but didn't receive them. The crew in the business class was not good in terms of service..

I had never seen any cabin crews behaving like that. They are not at all professionally fit for this job

Not so good. Issues with seat assignments, unruly lines during check-in, half a sandwich on an international flight. I was originally supposed to be on Qatar airways, but it was switched to Indigo after I bought my tickets. They wouldn't even let me get seat assignments from the US to Mumbai. I was automatically assigned seats, and a middle one at that. Terrible.

The staffs were very good and helpful especially since we were traveling with a toddler

Was unable to check in via app or website with supplied booking code (something to do with flight being operated by a partner airline, although the code didn’t work on the partner’s website either) Specified a vegetarian meal during booking, but that somehow wasn’t captured in airline’s system By the time flight crew got to my row, now vegetarian food was available. Had nothing to eat on flight from Philadelphia to Doha! Flight attendant was completely unconcerned and actively apathetic to the situation

Horrible. Boarding was terrible. For a huge airplane, we needed to be transported to the plane. The boarding area was overcrowded and frantic. .The seats were so uncomfortable. The food was fine.

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

There was a Turkish Airlines employee sitting in front of us, we noticed from her conversations we witnessed with the cabin crew and the fact that she boarded business class. She was sat in 16A. Firstly she was talking loudly the majority of the flight with two other men, one of which was leaning over the seat in front of her. This was disturbing as they were talking loudly and we were not able to sleep. The 12 hour long flight turned into a nightmare, even the noise cancellation didn’t work for their chatter. Secondly she requested extra meals from the crew for her male friends. We believe the meals came from business class. They also took their e-cigarettes out and were caught the cabin crew, but no further action was taken. Sitting in economy and seeing this is extremely disheartening. Next time I will book Emirites, I don’t think their staff would be allowed to behave like this.

seat didn't fold children noise in the air plain. no foot space

Okay experience, seats had a very poor legroom and width. Very uncomfortable for long journeys.

the worst experience we had. they put connection label to our luggages with mistake and we had to wait for 5 hours to pick them up

Traveling is Okay, but staying in Istanbul, specially Wi-Fi in airport terrible.

Friendly crew. Computer systems had trouble keeping my Star Alliance status linked to my reservation. Inflight Wi-Fi was slow and expensive. No standard power outlet, but medium-power USB-C port slowly charged my laptop. No option to buy whisky in economy.

Pathetic flight. No inflight entertainment and seats were very cramped

It has been a couple of years since I flew with Etihad last, after having a unpleasant experience with them coming out of the pandemic. I can say that the experience has uplifted, but I can’t really rate the service. At Barcelona airport the service was great, with their dedicated Etihad staff very helpful. The onboard experience wasn’t great, not very personalised and it really makes sense why Etihad doesn’t feature in the top 10 2023 Skytrax awards. The crew just seemed to be inattentive and almost absent from the cabin. I felt that I had to keep getting their attention. Even after I’d finished my meal, an hour went by before I had to call them to clear the tray/plate etc.

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

Crew was good, boarding mediocre, food choices were limited, seating was not comfortable
