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 😍

A very disappointing flight on this Emirates business class. Staff were not efficient and service was not the e usual Emirates experience. Good was particularly bad with very dry chicken and drinks that I had to press call button before getting a drink as my food sat and continue to get cold.

A very disappointing flight on this Emirates business class. Staff were not efficient and service was not the e usual Emirates experience. Good was particularly bad with very dry chicken and drinks that I had to press call button before getting a drink as my food sat and continue to get cold.

Worst flight I ever had I payed for special seats with underpriced which I never recieved. I will like you to make sure that I am refunded my 134.00 dollars that I paid for the seats that I never received. I am looking forward for Kayak to look into this issue with underpriced because they took my money and never booked the seats for me with the airline.

The flight experience was good, but connection time was cut shorted because of delayed start.. it would have been helpful if the flight showed which gate/terminal we need to go for connecting flight and flight timing was less than 30 minutes to connect which made ourselves stressful to catch next flight 😔

Good food and staff. Flights were delayed making catching the connecting one tough with no time to stretch in between

I am vegan. The food was balanced, tasty and enough. I enjoyed the ride. The crew was very friendly and went out of their way to please the passengers.

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

The first class experience was great but Frankfurt airport is very confusing. Badly signed all round. Boarding was not pleasant and check in staff was arrogant.

The internet connection did was not functioning as per normal.

All was good. Emirates should restart allowing fast track immigration for business class at Manchester airport. Saves a bit of time

Everything was good but I think food choices could've been better

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

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

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.

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.

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

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

The flight was very late, sitting on the plane for over an hour and missed our connecting flight from Singapore to LA. As senior citizens, we were rerouted to Copenhagen and then to LA. They should not do this to senior citizens. They should have given us a hotel voucher for a night, then catch a flight to LA the next day. Singapore Airlines should grant us some kind of credit for the next trip, if they want us to fly with them. I doubt if we will ever hear from them.

They bumped us up. They overbooked the flight and we hurried to the next flight. We are a family of 5 with 13, 10 , and 6 year olds kids. Everybody was running to the next flight. We never been exhausted in our flights hust like we have experienced this week. Mismanagement in scoot and kayak.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

Lost Baggage - very frustrated…learned that bag was never put on plane.

I think it’s time that somebody set a standard for the temperature in the cabins. I would rather it be colder than anybody that wants to have a blanket have a blanket to keep it so warm at times is unbearable and quite uncomfortable. That’s the only thing I would add.

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

Crew were professionals. However, the plane seats are too small -essentially there is no space to move around which for so many hours is almost inhuman but certainly unacceptable. Same with the bad quality of food and the fact that you need to purchase Wi-Fi

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

I had a good experience With Lufthansa, although on one of our seats, the headrest was broken and kept falling off. The only thing that would make a better experience if the seats in economy were not so small as when one pulls their seat back it leaves you very little room.

My baggage got struck in Rome while coming back from Hyderabad - SFO I missed my connection from Delhi to Hyderabad, and they were offering me a flight 3 days later. I had to purchase my ticket to go to Hyderabad.

The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.

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!

No refreshments apart from a bottle of water. No pillows. No entertainment. Flight delayed by 52 minutes.

Generally everything was OK,except the food but that seems to be a normal tendency for all the airlines nowadays

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug in was broken, especially we are with 5 years old who like to watch a movie

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

App totally screwed me up trying to check in. Would not let me select a reasonable seat and therefore I was stuck in a totally uncomfortable seat for 7 hours. Will not take the chance again and use other airlines in future where no issue choosing seats

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

Not being stuck in the middle seat between strangers but that’s not the airlines fault

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

I was at the airport 10 hour early. I would have loved to drop luggage in advance but this was possible only 3h before the scheduled time, however BA was so kind to move me to the earlier flight as it had space available at no extra cost. Thank you!
