Great flight attendants as always, they were super helpful and friendly. Made my kids super comfortable during long flight. The food were fine, some great taste some not so much specially the scramble eggs thats too watery. And maybe since its general food, better to not serve coffee pudding that kids cant really eat or maybe just serve different pudding for kids.

Great flight attendants as always, they were super helpful and friendly. Made my kids super comfortable during long flight. The food were fine, some great taste some not so much specially the scramble eggs thats too watery. And maybe since its general food, better to not serve coffee pudding that kids cant really eat or maybe just serve different pudding for kids.

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

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

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

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.

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

The crew was so kind! I had such a nice flight !

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

I want a refund. I had to switch flights and buy another airline ticket because this one was delayed.

It was ok, but not what it was like 20 years ago

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

My flight from Dallas to Sydney was cancelled. My entire trip was rerouted to include the following: Hartford to Washington DC Washington DC to JFK JFK to Auckland Auckland to Christchurch I paid for an aisle seat on the flight to Auckland and was asked if I would take a window seat to accommodate a family. The agent at the podium failed to mention that the family had a 3 month old baby and that a bassinet would be used during the 16 hour flight. The only way I could get out of my seat was to crawl under the bassinet of the sleeping baby. I think it is wrong that I was no given the choice to sit in another seat, that the agent knew what she was doing and chose to not properly disclose my seating arrangement. Terrible treatment.

Loved the staff. The economy seats could have been bigger.

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

Meal definitely May be better as well as games (not at all) Flight attendants were ok- however cannot say that very friendly I loved that there was reasonably enough place for legs and third seats near us was not occupied

Old plane nothing worked no charging facilities for phones etc

IFE didn't work. Wifi didn't work but they eventually managed to reset it. Our original flight was cancelled, so rebooked onto new flight seated apart from travel partner.

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

In never flown this flight, because my flight coning from Barcelona was delayed.

Lovely crew - comfortable journey despite it being an older plane.

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Everything was great. Cabin Crew was awesome and very helpful. Thank you so much.

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

The service and courtesy of the flight attendants was good. The check in staff were ok. Seat on the flight uncomfortable.

The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

Poor experience overall. The British Airways check in and bag drop at Palma de Mallorca was horrendous, took 1.5 hours to get through the queue. The plane air-con was dripping on me the whole flight and at times hailing small ice balls. Staff did not help at all.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

The British airways from Dallas to London is not great , the food is not good at all but BA from London to Delhi is amazing food is great.

It made me feel safe that the crew diligently check our seatbelts. One crew member was so very patient with a passenger in explaining to him why his daughter’s car seat had to be buckled in a certain way. This passenger and his wife were quite argumentative and she maintained her composure brilliantly.
