Poor flight aircraft very old Crew was friendly 1 person though

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

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

I have a very good experience flighting with emirates. All my expectations were fit well.

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

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 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.

All was good. Emirates should restart allowing fast track immigration for business class at Manchester airport. Saves a bit of time

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.!!

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

The food options and quality could use some more excitement and variety.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

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.

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.

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

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.

Fly Qatar Airways is always amazing. Their service and care for details is really very good.

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

To many ads. 3 or 4 between each movie. All repetitive, all related to Doha which I was just passing thru.

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.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

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.

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.

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

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.

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

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.

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