Enough vegetarian food was not available on the flight for all vegetarian guests on the plane. Crew did not adequately handle this experience

Enough vegetarian food was not available on the flight for all vegetarian guests on the plane. Crew did not adequately handle this experience

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

Absolutely horrible all around especially for such a long 13-14 hour flight - terrible food - ancient entertainment - legroom worse than a short air Asia flight - not enough toilets

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.

Emirates is still my favorite airline. The good, entertainment, crew, and value are excellent. Unfortunately, the flight was delayed taking off and arriving - which caused me to lose my ground transportation plan. While delays happen, more communication about the delays would be helpful.

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.!!

Flight was delayed and no information was provided what was new time Change gate 3 times at Madina airport First gate was 113 Second gate was 204 And last gate was 113 again

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.

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

Food option Hindu veg to Hindu non veg request was unheard

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

It was a middle of the night changeover, so we were all ready for sleep. Staff were helpful and managed a few hours sleep. Food options were good.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

There was not enough food for everybody. Some dishes were missing.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

There was frequent beverage ,meal and snack service. The crew was very hospitable and professional.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

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

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.

They have misplaced my one checked bag which I have not received in Philadelphia and have lodged complaint with American Airlines, the staff of Indigo was rude with us, at the checking counter, I think she purposely withheld my one of the checked bag, because the American Airlines staff told me that bag was not received at Doha airport. Kindly help me with one of my checked bag to get it. My flight was from Mumbai to Doha and then Doha to Philadelphia.

It was pretty good overall. I just wish the crew didn't have to interrupt you every five seconds to ask you if you wanted anything, I mean that's what the help button is for. When someone is tired and sleepy and still getting their bearings, turning on DND button is maybe not the first thing on their mind.

Good food and wine. Some of the Guy who are in charge to board Passengers on the plane couldn’t use the word “Please” to direct them drop their hand luggage to be loaded on Plane bcos he said the inside storage may not have enough room for all.

Excellent service. Made United 's business class look like a cattle car

Food could have been hotter. More padding needed in economy seats

Crew was good. Plane and seats were cleaned and good. Food and entertainment system was bad.

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.

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

Flight was overbooked. Luckily there was room in Business so several people got free upgrade.

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

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

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

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

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

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.
