Check if there are seats at the rear configured as 2-4-2. The extra space on the aisle is very good to have.

Everything was good; they still provided a sandwich snack. Good crew

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The crew could have awaken me to eat dinner!! I was so waiting to order the braised duck breast and fell asleep b4 crew got to me to take order. When I awoke, lights were out and food had been served without me eating. I did love the apple juice!

Boarding was good and efficient, however since this was a late flight I spent most of the time sleeping so can't express any further opinions

Previous flight with Cathay from LAX was delayed thus missing this flight to KL by 12 hours. This in turn missed other travel arrangements from KL. They did provide overnight accommodation in Hong Kong.

The flight was delayed for over an hour, which made me worry about pets in cargo.

It was good, on time boarding. Have a good service. .

Better food quality and suggest using the 777 for the HKG-BOS leg instead of the A330 since the seat pitch seems better on the Boeing.

See previous answers. Also food options limited, entertainment difficult to use and did not work properly, lay flat bed is quite big but very hard and uncomfortable

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

Boarding was very chaotic, we had to stand in two different lines that were not clearly marked, and the announcements were not understandable from the microphones, and we speak both German and English. We paid Kayak $120+ for seat assignments when we purchased our tickets but when we printed our boarding passes, suddenly we had been changed to 16 rows further back than our assigned seats we paid for. The seats we were assigned to on our boarding passes had no usable overhead bins and so we had to sit with our carry on backpacks underneath our feet in an already crowded space. One video/entertainment screen kept crashing and thus was useless for viewing anything. It was not an enjoyable flight.

The Swiss airline is excellent. Seats ate comfy, spacious and free wifi that I enjoyed a lot on my trip

Everything was fairly easy just hard when you get to Heathrow not know your Gate number until an hour before but otherwise really everything great. Did not get my texts in time though to do me any good but that is why I still like everything the old fashioned way and print everything out.

The cabin was warm and few used the blankets. I should’ve upgraded.

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

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.

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

Stuff was very helpful at checkin. Flight attendants were nice. Food wasn’t very good, I expected a little more. Economy Seats are ok. Second flight was very full and they forced us to checkin our carry on.

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Weren’t even given earphones to use the entertainment system

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

Pillow and blanket are dirty. My son got multiple bites during the flight

Excellent experience however older aeroplanes used by China Eastern Airlines.

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

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

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.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

Poor experience overall. The British Airways check in and bag drop at Palma de Mallorca was horrendous, took 1.5 hours to get through the queue. The plane air-con was dripping on me the whole flight and at times hailing small ice balls. Staff did not help at all.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

The British airways from Dallas to London is not great , the food is not good at all but BA from London to Delhi is amazing food is great.

Ticketing was a bit misleading. Was not immediately apparent that the tickets included no check-in luggage allowance.
