We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

The staff on board were excellent. Kind, thoughtful, helpful - not just with me but with others around that I observed. Wonderful service.

The queue for checking for economy passengers was enormous! Only one desk open for economy faith s queue a mile long, whilst business and first class desks empty and unemployed. Will seriously consider changing to another next trip. Disappointed customer.

They should resume the fast track for business / first class passengers

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

Poor flight aircraft very old Crew was friendly 1 person though

Amazing and great experience, crew was available and took great care of my parents. Food was nice and so was the service. Aircraft from Dubai to Mumbai was not so great and was a big showdown of the aircraft service

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Food from Surabaya was below average but from Singapore is much better

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

It was very good experience on board to Sydney with SQ.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

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

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

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

The food could be better. Toilets were smelly all along

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

Should have had business class line in immigration. Food quality suboptimal

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

My first two flights were late. I missed my last flight. The next flight was not until the next day Seating on large plane was uncomfortable. In the center row, there are posts that do not allow you to spread your legs. The entertainment center did not respond well. . Food was okay. Though there was much confusion about where the special meals that. People ordered(not me) went

Leg room is good, food is average, crew is not friendly

Lufthansa has outsourced their ground crew to a company in Bengaluru. This company is really not dedicated to customer service. Very disappointed as this does not reflect Lufthansa’s service that I remember from before.

No complains with the crew. But generally speaking food is awful, entertainment is not good either.

Boarding was smooth and efficient (no waiting on bridge and in plane). Flight crew was very much focussed on passenger comfort.

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

I was told to be there to check in three hours before my flight and the counter only opened up two hours before. Apparently that is standard. So that was an hour I could have spent walking around Larnaca that was wasted. But besides that it was great

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

I enjoyed the comfort of Premium Economy. The Purser on London-Nairobi was a little testy, snappish in his tone. I understand stressed, tired, etc but his tone in addressing passengers I found wanting.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

British Airways Flight 525 from Florence to London on July 29th 2025 was the worse flight I have ever been on. The flight was excessively delayed with poor communication from airline as to the reason for delay. We were notified of need for an unscheduled stop in Pisa after boarding due to weather which was limiting ability to fuel up to the capacity needed for the flight to London. Though we understand and appreciate the safety concern, on quick web search we later learned this was a recurrent problem. We were subsequently kicked off our connecting flight out of London to Port land, Oregon (also on British Airways) though that flight was also delayed (we were told we would not be able to make it in time, but ironically the amount of time it took for them to rebook us would have been more than sufficient to make the connection). We then had to stay overnight in London at a very mediocre hotel, had to take a flight out on a different carrier which involved a stop at LAX (not a direct flight to our home city which we had paid extra for the convenience). Half of our bags did not arrive in LA and we had to transfer the bags ourselves from the international terminal to terminal 6, only to have most of this luggage that made it from London to LAX not arrive in Portland. They bags were eventually found but took over 60 hours for delivery. The entire trip home which was suppose to be 13 hours took over 40.
