Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

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

The seats were more narrow than at other lines. Food was mediocre (economy class)

Service excellent would chose Singapore airlines as my first choice

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.

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

The male traveller seated in the row in front diagonally opposite my husbands seat across the aisle as soon as the seatbelt sign went off moved across the aisle into the seat in front of my husband for the entire journey from London to Singapore he had his seat reclined and pushed back and the seat touching my husbands knees for the entire journey from London to Singapore. very uncomfortable for my husband.

More Baggage limit Alternative of virtual check in at airport , prefer personal touch with “real person”check in counter for baggage drop

Excellent customer service from pre boarding to the end. Really enjoyed my flight. Very helpful crews during flight as well. Will definitely flight with Singapore airlines again.

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

Delayed 30 mins Forced to check in my carry on luggage

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

It was not made clear that additional passport control is needed before queueing up for boarding. The seats were very uncomfortable and cramped even for small persons. The arm rests were not fully capable of lifting up out of the way and the media controls cut-out made them even worse to lean on. Just one audio channel was working on one of our seats.

Not much that I liked. The seating and Space between the seats was very bad for long flights.. very bad for such a prestigious Airline.

Flight was late on arrival. When asked, one of the crew was not helpful with providing us information on if we could meet our transition and would only say to listen to the announcement. We nearly missed our transition because we had to race across the terminals. In addition, our checking bag did not make the transition. After making the report, no calls updating us on status were received. Provided my telephone number, but when I called they said they did not have my number. I still have not received my bag

No fault of the crew, but the the rear lavatories were closed the entire flight. The front lavatories were blocked off for the first part of the flight by the food cart. Then some minor turbulence occurred so the fasten seatbelt sign came on for the second part of the flight. Heroic containment engaged! It was not fun.

I have paid extra money for my special meal service but I received the the local food. Which is not acceptable.

More entertainment channels and better food, whatever food requirement you select.

The flight from NY to Bangalore was very good but the return flight from Bahrain to NY was mediocre

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

Very poor experience, passengers and were not social and started a troubled with other passengers and a fight erupted

The drinks should come before food. Unable to have any fluid unless after food. Thanks

Aereo nuovissimo e con tanti servizi malgrado la durata del volo Spazio per le gambe ridottk

Aircraft was new and comfertable .on time. Cabin crews, which I got english language pronounce was very difficult to understand .ovee all ok flight

The boarding at Heathrow is chaotic. That's partly due to the lack of space and seating at gate 8, and a Qatar flight from gate 9 at the same time. That's down to Heathrow rather than Gulf Air. I've had a similar experience here before. Another problem which isn't specific to Gulf Air or Heathrow is announcements, and those for boarding in particular. They are difficult to hear with all the other noise and for me with hearing problems it's even worse. A simple tv screen would help, so long as it's updated of course.

This itineray had to be cancelled as the connection time in Paris was only 55 min which is below the 90 min required by Paris airport. Nether Chat deal/Kayak, nor Gulf air nor American Air picked on that. I called American Air for unrelated question was then told that boarding would be denied due to the short connection time. This should have been an automatic notification from Chat deal/ Kayak or Gulf air and itinery cancelled. What is the point of inconveniencing the passenger?? The return has still not be refunded. Shame on Gulf Air, very poor customer service for an airline that has so good flight crew!

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.
