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

Take MAS for its Malaysian Hospitality & you’ll never regret it 😍

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

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.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

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.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

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

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

Edelweiss is now Nickle&dimming, not even a complimentary wine on the intercontinental flight. Sitting space is the smallest I have ever seen.

I would recommend flying SWISS to anyone. Very impressed by the quality of food. The staff was extremely kind and accommodating. They arranged a shuttle to help a group of passengers make connecting flights when there was a delay.

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.

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.

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

We lucked out. The passenger who was supposed to be in our row changed her seat, so my husband and I had 3 seats for the 2 of us. We were able to stretch out a little which made the trip much more tolerable.

Much better than I expected for such a long flight.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

Top notch service, good selection of snack and meal options, generous accommodation for luggage, and great selection of in cabin entertainment. I really appreciate the offering of pillows, blankets, sleep mask, tb&paste, and earplugs. The only complaint I can make was that my seat was horribly uncomfortable and lacked cushion.

Don't irreparably damage my luggage, don't stand around talking in the kitchen area of the plane when a passenger is waiting to speak to you, don't run out of a meal selection so have me end up eating bread for dinner. Lastly, regarding the code-share flight from DFW to JFK....STOP PARTNERING WITH AMERICAN AIRLINES - THEY ARE THE WORST AIRLINE IN THE WORLD! The delay, followed by another delay, followed by disorganized boarding, followed by stale snacks fit for a rodent, followed by a pilot who literally slammed the plane onto the runway when landing causing quite some concern among the passengers.

Perfect. The flight was on time and the crew were very friendly and helpful.

Boarding was unorganised. The flight was very uncomfortable, the temperature was far too high. On requests to lower it nothing changed.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

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.

I had to fly United where the flight crew was atrocious

Flight delayed at Newark by more than 1 hour. Weather was perfect. No explanation provided. This delay made me almost miss my connecting flight at Munich. Bags from all passengers from Newark were NOT loaded onto the connecting flight to Munich. Two days without fresh clothes.

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

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!

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

Staff and crew where very nice and friendly. Just need to improve the timming om the meal and beverages.

3 hr delay. No water given while on the plane for 3hrs.

Excellent except for checking in at Madrid Airport. Waited in line for over an hour and a half. Not enough ticket agents available and they were moving those with earlier flight times up in order to get them through. People were not happy. Staff did their best to explain, but just not enough to meet the need.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

I will travel by BA only in future also. Only suggestion is they should give aisle seat in front near washroom for senior citizens

I'm a world traveler for the 30 years. The WORST AIRPORT i've ever been in Totally over booked They shuttle u around MANY TIMES TO GET to planes and gates They over book and have massive delays Will never fly BA again

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

More than 3 hours delayed. And they knew about it the night before already. I had a laugh when the captain said - don’t take out your frustration on the staff. Before take off Business class seats had very little space. My knees were digging into the seat in front
