When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

Transfer within the same terminal and lots of facilities at the airport.

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

Check in was snails pace, only 1 of the luggage screen was working so long lines, an hour to check in Nobody seemed to want to fix the issue Flight was 45 minutes late Scoot is a mini sized plane ( sardine class plane), literally felt slammed between people

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

Overall good but one thing I didn’t understand is why they didn’t allow me to pick my own seat.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Excellent airlines. I highly recommend using Emirates. Its my number 1 airlines

I bought Business class ticket but they treated me like economic class. No lounge allowed at check inn I have to take stuff out while other passengers have more than 25 lb in bag. Because I bought tickets from other than airlines . It’s discriminations from airlines to passengers.

Overall emirates continues to amaze me with their. Awesome service . I had shifted away from emirates , because I lost luggage and watch in emirates in 2019 that drifted me away from this airline , but I am willing to give it try

The amenities offered in the Business class is far away less compared with other Air Companies. Emirates is going down in the competition pricing the same value as Qatar airways for example.

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

We had a connecting flight which is got delayed they didn’t transfer me to another flight and up I have to by 3 new tickets and I have to pay extra luggage fees cost me rs 100000

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

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

My seat that I booked over a year ago and some other passenger was sitting in it. They said they could not walk and they would not move. I was with my young kid and the crew did nothing to accommodate that. Just disappointed that the airline accepts that excuse from a passenger.

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.

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

The boarding process was unpleasant. We had hardly any checked baggage, but they insisted on weighing the cabin baggage. While the weight of our cabin bag was well within limit, it seemed petty! The food was pretty disgusting. I had such awful food on the way over, that I brought some snacks of my own for the flight back. Glad I did. Qatar was consistent in that food was just as terrible on the way back as it was on the way over. The flight attendants were super-nice, though. If I had an option I would not take Qatar Airways again.

Food could be much better. Entertainment needs lot of improvement. The luggage came out open with broken bags. The flight landed at 3:15 PM in US and by the time bags came out it was 5:15 PM or so. Staff at airport was aggressive and not polite.

There was no phone charger, uncomfortable seats, unprofessional flight attendants, didn’t like food. Could not reserve seat in advance

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

Sky priority means you get to use the KLM business Lounge.

Je n'ai pas pû incliner mon siège et une des hôtesses ne comprenait pas ce que je disais. Je devais parler fort

The crew was great and handled our unexpected detour with proactive communication.

I paid extra for a seat with more leg room but they changed the plane and found myself in an ordinary seat. This is expensive at 50€

Seated in business class. Bed too hard and no comforter. Way too many seats in business class for number of crew so never felt particularly looked after.

The entertainment system in our row was not working. That makes for a VERY long flight!!

I was called up at the gate not knowing why and then handed over my passport and was told I was being upgraded from Premier economy to Business class and it was wonderful. I've never been upgraded before and it was such a pleasant experience.

Horrible experience! We sat in the plane at the gAte and had a delay of about 4 hours! Captain said it was due to the tug not being able to disengage from the aircraft . When we finally took off it was evident that we had missed out connection and tbough BA rebooked us on a later flight it caused us to miss an orientation meeting and dinner in Geneva. Once in the second flt from gatwick to Geneva we again were delayed( again sitting in the plane )for an hour after boarding waiting for apparently an air traffic problem to resolve. Another annoyance was paying seat fees twice to upgrade our seats towards the front of the plane to ensure overhead cabin space and were told at the gate they are boarding from the rear! This should be stated when making reservations!! On the first flight from Jfk there was a sick person on board snd they asked for assistance. For the rest I of the flight a person kAyed on the glue if the planes covered in blankets . Very unsettling to say the least!I have several flights booked with BA and I’m seriously rethinking this. Kathleen Ditta

Wonderful staff, as always. Arrived in time despite delay taking off. My airline if choice, always. Thank you!

You lost my luggage on the trip to Dublin and again on the way back, still waiting on luggage.

Boarding in Miami was chaotic. Gate crew lost control of the mob! Onboard crew very impersonal. Food was ok — not as good as previous flight. Landed ahead of time.

Supervisor at the check in area was very rude, unhelpful and unprofessional. Checking in was rowdy and stressful. Boarding was the same. Food on flight was horrible. Could not get drinking water onboard. Told by flight attendant that they had limited supply. Flight attendants were very disturbing throughout the overnight flight. They cared less about passengers trying to sleep and kept bumping into people as they walked along the aisles with their bodies and trolleys. Just very bad and disrespectful experience.

Everything about the flight was great. One negative thing, The British airways site said that we could check one bag for free but American Airlines who was actually doing the flight charged us 70 euro.

Excessive delay without proper communication. Mediocre for a BA flight.
