A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

The experience was poor in comparison to the flight to Manado from Singapore via Scoot. Gate against could only check in stroller to Singapore (by clearing immigration) or to Brisbane. Who is able to carry their baby for 7 hour transit without having to enter Singapore?

I loved the comfort of the flight and the hospitality of the flight attendants!

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

If I made the connection in Singapore I was stuck there for 24 hours you owe me 355.00 for accommodations

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

My experience with Scoot is very good. Will have no issue flying with Scoot again.

Great to have actual hot tastey meal on a flight. Well done

All in all the flight was good. Love the fact that for airline food it was piping hot

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.

Very good!! If at all, the business class chair/bed was bit small!! It’s because of older plane- as was told!

The food was pretty good and the crew were excellent. It would have been excellent all round but for screaming children. Six hours at least of a 10 hr flight. Mostly 1 child clearly on the spectrum and probably ADHD but I really felt for the parents and grandparents who were obviously struggling and doing the best they could under the circumstances. No reflection on the airline of course and we all need to be more tolerant with these challenges . Slept for 15 hrs when I got home.

The boarding experience was worst ever. Single aerobridge used for boarding and deboarding which led to lot of chaos. Food options were not great. First flight delayed by more than 3 hours which led to missing of the next flight we were stuck at Dubai airport by more than 6 hours

Surprised how empty comfortable seats in economy were not offered by crew to tall passengers. Felt like courtesy hall mark of emirates is changing. We were told in order to get those seats we have to pay $210. Not the emirates I know from past travels.

The plane was very old and uncomfortable. Service was very slow!

The first class experience was great but Frankfurt airport is very confusing. Badly signed all round. Boarding was not pleasant and check in staff was arrogant.

Much better this time than our previous. We had Been thinking we wouldn’t fly with emirates again. I have a wheat allergy so request a gluten free meal. The meals provided in the past have been mostly inedible. So dry and hard and tasteless. I see what my husband gets given with a packed tray with treats and mine is uninviting and awful. I actually was hangry with little food and not able to eat and enjoy what was given to me 😡 This last flight was an improvement. The first meal was edible tho no treats, why can’t a chocolate be given like on the regular trays. I realise you are trying to make the gluten free a dairy free and probably vegetarian one at the same time to save you dollars tho it’s shocking to receive. The snack sandwich given was much better and edible, not hard and dry as previous trips. The final meal received, Breakfast had more variety and treats on it, thank you for that. At last.!!

Emirates is always great experience, however, they should reopen their lounge in Istanbul. The IGA lounge is not worth it

I liked everything accept the delay try to improve in that area

The food on this flight was just terrible. I have a wheat allergy so when booking I ask for gluten free options. The food given was inedible. The bread rolls were rock hard. Once board I was given one and the only thing I could do was eat the chicken slice and piece of tomato on it. Also given was 4 small cubes of fruit, 2 watermelon and 2 pineapple and a bottle of water. My husband had a regular meal and found his very average. Then the evening meal was also disappointing! Some dried out fish with spinach and 3 sticks of dry white sweet potato. No sauce …. 😳 again, the same fruit and water. The passengers had to wait a long time for the dinner food to be served. My husband just wanted to eat and go to sleep so he was a bit annoyed about that. We got off the plane and I was feeling quite hangry. Not enough food or a good eating experience. Emirates used to be a flight we looked forward to… now we are considering looking at other companies for the future.

Do not overbook flights and kick out confirmed ticketed passengers :-(

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Don't be afraid if you board an Oman Air Airbus A330 - it will take you to Colombo and not Muskat. The Aircraft is leased by Qatar Airways ;-)

Good staff, good intent, decent entertainment. More seat space would always be of benefit

It was a long flight but overall a good one. The one thing that I would comment on is that there is a real problem with disposable plastic products when it comes to the meal service. It would be great for Qatar Airways to find ways to make its meal service more circular and reduce the immense amount of waste.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Just money making business. This was my fourth journey with Qatar Airways, year by year the quality of service getting poor. Food is very cheap. They have some low quality alcohol beverages. They don’t have any brandy or cognac. No toilet around the gate lounge. We have to wait until getting to the flight for use toilet.very long standing for entering into the flight. We can see the old passenger suffering.

I didn't understand why I got dropped off at departures on exiting the plane at Doha aiport. I had to find my own way to immigration/baggage reclaim which wasn't easy as staff in the departure section just tell you ti scan your boarding pass. This was very poor b qatar Airways. I spent 2 hours soyung this out and once I got to get my suitcase it was delayed. So instead of getting to the hotel at about midnight I got there at three in the morning. I wonder why I upgraded to business?

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

First was canceled no compensation second day was delayed Worst airline I have ever seen

It was a good experience, it was just the the connecting flight after that was a problem.

Stale, bad and limited food, drink options. Entertainment system was broken, old and had barely any latest contents.

Boarding via busess, like low cost airline. In their domestic hub. Insane!

boarding from the lagos airport is always very chaotic. The seats on the place are not comfortable (old planes are always used on this route) and the screen chargers for my phone are both not working (both seats).

Food was horrible and not suitable the world famous Turkish cuisine and hospitality.

Pretty good. I’m currently in Accra but my luggage is still in turkey so that’s inconvenient

On my flight the menus showed different food and different was available. I think that was a miscommunication maybe. Other than that flight was wonderful.

The flight was delayed dur to which I missed my bus from Chicago to Champaign.

I took a nine-hour flight in economy class, and the seats were quite comfortable. I even managed to take a long nap, which rarely happens. There was a good selection of movies, and the complimentary kit included socks, ear plugs, a sleep mask, lip balm, and a toothbrush with toothpaste.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

Etihad flight sector is a local . .give the same quality upto destination

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience.

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.
