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

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

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

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

Very bad groud crew taking bags less than 7kg Bad food Old plane

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

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.

The flight was nice and on time. The comfort can be slightly better in business class

The food options for children is limited The business class bed is not fully lie flat, and this is an uncomfortable sleep

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

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

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

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

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.

My luggage did not make the connection and 4 days later I still have not received it.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

Seats are too cramped, but that is a problem with every airline. I actually enjoyed the meal served.

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

Lots of water brought around by staff which is very important to stay hydrated on a long flight. There provided swiss chocolate icecream! The attention to detail is obvious. They really want to make their passengers entertained and comfortable.

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

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

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.

This was an upgrade to business class and really enjoyed the experience. Much better than my earlier flight and thank you.

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.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

BA have long since lost their way. They are a budget airline without the budget fares. Everything from booking to boarding to flying to arrival is just plain ordinary. I fly BA if the only alternative is Ryanair who are even worse. Otherwise we fly KLM or Lufthansa who are so much better.

An hour to check-in because they were not organizing the counter personnel well; they lost my baggage and after 48 hours they so not pick the phone, answer emails, and I still do not know how to claim my essentials (its purposely not their on their "help" page).

Courteous and warm. Good experience while traveling back with an infant.

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

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.
