It's 14hrs and feels like it. Pay the small amount extra for the "premium economy " seats- there are 3 rows in a separate cabin and it just feels more relaxed and comfortable with a bit of extra legroom

Flight left on time. Bags came quickly. Crew was nice. But internet never worked and the food was awful.

Flight was delayed by and hour but were informed beforehand

Delayed, Bad American style food (not tasty, horrible cheese for a flight to France). Incompetent cabin crew (I asked how to connect by cable my headphones and the flight attendant suggested me Bluetooth which is not available). Good space

On this flight, about the last 2 hours the captain kept the cabin too hot. It appeared like the ac was off.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

Airline did not have enough vegetarian meals for all guests, and crew were not adequately trained to handle this.

Nothing, all that I know is that I will never travel with Emirates again Qatar is were I belong. You guys should send someone over to experience what true acomadation is, Emirates has the worst food that I ever eat on any airline ,even jetblue has better food and snacks that curry Indian garbage you guys serve just make people sick.

I was not allowed to upgrade with miles whereas others were. That’s a pity

The staff were very friendly and helpful. The seats were very comfortable and spacious. The entertainment was amazing, and so was the food!

Excellent staff! Flights were delayed due to technical issues after everyone was boarded and we sat in the flight for almost 2 hours before taking off. Not enough vegetarian food was available despite pre-ordering. The staff did an exceptional job dealing with both the problems neither of their making.

Everything was great keep up the good work 😁, can't ask for more.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

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

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

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.

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.

The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

I like how professional, fast and good the whole experience was.

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

better announcing at the gate prior to boarding and better organization of various gps

The plane was good - on time! But can the stewardesses smile or actually be nice - not to bark the commands

I have no complaints. The crew was attentive, pleasant and heloful

overall the flight was good and we were happy they waited for us. However, our luggage didn t make it and this caused us a lot of problems.

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

The seats had no space at all beyond the knees. The seat in-front literally reclined on your face, very uncomfortable plane. Was nothing like the normal SWISS experience. The food was okay but could be better.

It was the first time in my life (I’m 54) that I’ve had to pay for drinks on an international flight. Very disappointing. Also, the baggage fees were very steep. I’d rather pay for everything in the price of the ticket than be repeatedly charged for add-ons.

It was unclear that additional passport control was needed before boarding. The seats were cramped and uncomfortable even for small persons. The arm rests were unable to be lifted completely out of the way and the media controls cut-out made them uncomfortable to lean on. One audio channel was not working on one of our seats.

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

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

Good staff help. Seats do not have enough legroom. Bus from plane to terminal was annoying.

No assistance as requested. Very late take off. Very hard landing And again , no assistance after landing

Be on time. Constant delays, missed connections. No excuses. Weather was not an issue

Slightly delayed but still a more comfortable experience to take a real airline instead of a budget one.

Due to flights being delayed, we missed our connecting flights and we were flown to a different airlines and we end up losing our luggage's.

While booking through Lufthansa, when flight is operated by other airlines, you don't necessarily get the quality of Lufthansa. That said, I was passed over on both meals served. While I had my eyes closed or asleep, no attempt was made to serve me or wake me for the service, which is something new. When I took it upon myself to get out of my seat, track down an attendant, and ask for a meal, the attendant would kindly serve me. Of more concern, however, is the lack of selection for the meal. Being diabetic and insulin dependent, I could not eat what was served. The first meal was pasta with a small slaw/salad and a bun. The second meal was a muffin and another pastry. In all, I could only eat the salad, which amounted to next to nothing. Fortunately (for Discover) I had brought food/snacks to carry me through the flight. Otherwise, I might have reached a low blood sugar. With diabetes becoming more prevalent, Discover may consider more eating options to accomodate all passengers.

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!

It was just ok. Half the bathrooms were broke on the flight.

Was very bad the cancel the flight after when we arrived to London

1. Missed to deliver bags at Destination 2. no coordination at Layover for flight connection for wheel chair , could have missed flights 3. Customer service agents are not honest , talk with attitude and do not provide correct information about baggage policy

Denied boarding passes for connecting flight. Missed connection as a result. Customer services T5 Heathrow airport vile, arrogant people who lied to us and threatened us.

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

The flight was severely delayed. The check in desk was rude.

Everything worked well. But nothing really stood out. BA is a reliable work horse for international travel. Moderately priced, reliable but not outstanding in any aspect. I will definitely use them again. The morning flights out of India a definite blessing.

Horrible. The Athens to London flight was horrible. At some point there was a long piece of toilet paper on the corridor floor for 30min, crew were stepping over it. Only picked up when they rolled out the garbage cart. Not a pleasant site. The whole experience reminded me of easy jet. Not worth the price.

Didn’t make flight and then forced on connecting flights back to LA that cost me another day of travel on an inferior experience.

Food was average. Better headphones seats were average at best.
