I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

The seat and leg room is small on the 2 seated row. Otherwise, very good crew and service.

The meal was wonderful and strawberry ice cream was a plus.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

Great food - movie selection was good. Plane was a few minutes late but got to destination on time.

It was great! Friendly crew. Good food and service. Great snacks. But one of our luggage did not come to Chicago. Stood at carrousel until the end waiting for our bag and it wasn’t there. Then we had to rush very fast to catch our connecting flight to Cleveland and almost missed it

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

Turkish airline is so mismanaged . We had to onboard a flight outside from tarmac when there was heavy rains . By the time we climbed the flight we were drenched from the rain and we were so cold. The flight service was so terrible. The flight attendant never responded to any of the calls. There were no extra snack left for the kid . On one of the more than 13 hours flight my seat did ot recline and the person in the front had reclined their seat completely , for the whole more than 13 hour journey , I barely had any space to do anything . I will never travel with this airline ever again , such a bad experience

Poor connecting flight logistics and ground transportation for such enormous airport. Airline does not consider time required to complete the security check or transition from one to gate to another

Unbelievable food and service! Chefs are amazing onboard. WiFi spotty

Boarding was chaotic. Cabin noisy. Temperature a bit cool. Bathrooms not cleaned enough.

3 of us were in the business class. All good except the Flight out of Mumbai is too early. It is at 6:30 am. Reporting is at 4 am. We had to get up at 3 am. US connection has 4-5 hours of layover. It would be nicer to start the India flight late (give more time to sleep at home) and have less layover duration in IST.

Okay experience, seats had a very poor legroom and width. Very uncomfortable for long journeys.

Service was superb and the flight experience overall was great

My mother got sick and dying and i have to change my flight and they charged me $2260 that is redisclose.

My whole body was paining after such long flight. Seats are small. Leg space is too small. Food is good.

Pathetic flight. No inflight entertainment and seats were very cramped

The crew were really bad mannered! And spoiled all my mood throughout the flight!

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

On this flight...fine. The one from India to Abu Dahbi, awful.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Crew was very courteous, friendly and professional. Caring and attentive.

Good flight overall But aircraft is little old- 747-400. Hence it is spacious compare to newer 787 dreamliners Asian vegetarian food was reasonably good

The checkin process was horrid because of a rude staff, the crew pretty much ignored the request for a bottle of water soon after boarding. Not all the crew were bad, but there are certainly some bad apples in there. This review applies to only the Frankfurt to Dallas leg.

Crew is good. Food lacked any taste. Comfort of seating in economy was worst ever experienced.

The flight was cancelled, and no reason was given. The flight was rebooked 3 days later. Calling customer service was next to impossible. There was no option to get in a queue in the phone call. It simply said all agents are busy call back later. It is 2024 and not 1970s to have such outdated technology. Live chat was even worse as I was 753 in line and it kept getting timed out. The icing on the cake was that the working hours was something like 9:00 AM to 6:00 PM? Really for international airline when the flights usually depart early in the morning? Things only got worse in the check-in counter in Mumbai. The monitor in the check-in counter said that the flight was on time even though it was cancelled. There were 2 agents helping a 747 full of passengers. It was 5:30 AM by the time I checked into the hotel. I tried reaching Kayak (Chatdeal via email) days before the onward flight from Seattle and no one cared to respond even after reminder. I will go with Expedia in the future. In fact, for my next trip to Japan I have already used Expedia.

Ended up canceling the tickets with Lufthansa because they need extra visa for changing terminal for layover at Frankfurt airport.

boarding in mumbai was a mess.. It felt like 80% of the flight boarded in the pre boarding section which was meant only for people with special needs and with children. The staff who were checking their documents just did not care if they were supposed to be in this line or not. Lets hope they improve on this

Better service to offer drinks in the middle of the trip

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

The staff was extremely friendly and nice. Overall, the flight was pleasant, and the food was good. They asked me to check in my smaller cabin luggage suitcase in Mumbai as the flight was full. Fortunately, I had packed a spare set of clothes in my laptop bag so I was okay.

BA is a fine airline. The problem lies with XCOVER INSURANCE, that KAYAK uses. Very poor service from insurance. No telephone number to contact XCOVER. Their replies are inadequate & overall very bad insurance. I wish kayak uses standard insurance company., such as AIG.

I missed my flight because I was sick and the medicine the chemist provided made me sleepy. I had to pay $3500 to get home because you classified me as a no-show and would not listen to me otherwise. In addition you wanted to route me through Dubai, which was under siege by the time I arrived home and would’ve been in trouble. Had I taken that route

Mumbai airport is a nightmare! Especially going from domestic to international terminal (2). I almost missed my flight. Then i could not check in because I purchased on kayak to British airways and my first flight was an indigo (non partner). So they called me when I was at the security outside the terminal and told me I had a middle seat, not what I paid for! After talking to the desk agent, they could not help but it finally worked out. A bit stressful for no reason. Probably never buy from kayak again this type pf complicated tickets (multi cities).

Aircraft was comfortable even in economy, clean. Entertainment screens were excellent and. Hoice was very good. Good was just ok. Crew was not bad.

Entertainment did not work from DC to London. Was not able to check in online during my return journey from Mumbai to London. Food was good!

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze, Sara and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

For a business class ticket the service was very mediocre. We had to ask for coffee after a meal and the service was grudging like we were putting them out. The leg from BOM to LHR was especially bad and the toilets had no water. It was disgusting. Looks like self service is the new model for Business Class. No Thank you. I will look elsewhere
