Check in procedure is harder than with other airlines, infotainment system is outdated

Checking in as an international flyer is a bit tedious

I liked- timely took the take off I disliked- food for ANML was not served even after request, ASVML was really bad, the cleanliness of seats were not up to satisfactory level and I had to use my own sanitizer. Even basic sanitizer packs were not served, cabin crew could be more friendly as I noticed their behavior against other fellow passangers who were not speaking English well.

It was okay, short flight so nothing much to comment.

The crew was attentive and provided everything I needed. The business class food was excellent.

The crew was attentive and provided everything I needed. The food in business class was excellent.

Fantastic flight company. A higher standard than any American airline company for sure.

I thought this was a JAL flight but landed up being a code sharing one with Hawaiian Air. Got upgraded by check in staff and they confirmed my bag coming from Bangkok which was great. Cabin crew was solid, not especially friendly, just super efficient and wanting to get the job done which they did. Very fast and agenda oriented. Worst part is my economy plus seat was no better than my economy seat on JAL. Plus JAL has way better food, cleaner plane, and better crew. Worst part is when I landed, was never told where to grab bags. I had correct flight name and number for JAL but there was a Hawaiian flight number in another baggage terminal. I wasted over an hour with no help from ground staff for my bag. Hawaiian and Alaska airlines merger can’t happen fast enough as Hawaiian airlines is a dinosaur. Bad experience again and I’m not surprised. JAL rocks!

Business class lie flat seat is the best and easiest to operate 👍👍

My seat had zero leg room. I thought I was flying Japan Airlines, a company I picked based solely on the legroom... When I got to the airport on my first flight, they informed me that I was in fact flying J.A.L VIA American Airlines... What a bait and switch. I will never fly AA on an international flight ever again.

I wish there were more bathrooms available on these larger carriers.

The experience was efficient, on time, and provided great service.

Trip was fine. My only complaint was that when the passenger in front of me reclined her seat (which was, in essence, the whole flight except landing and take-off,) it was uncomfortably claustrophobic for me and very difficult for my husband to get in and out of his window seat. Also uncomfortable to watch the entertainment because the screen was right in your face.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Overall, not good. Super late boarding in Hong Kong because some last minute issue with a plane. The boarding process is chaotic. Kathy Pacific should seek to do better with punctual departure time. Caused a lot of trouble with missed connecting flight.

It's basically 15 hours with an airline in economy class. There's really not much of anything that could have been done better unless I had a first class ticket. Cathay Pacific does excellent work, with a very professional, friendly and attentive crew. It's literally the only airline that I will fly to Southeast Asia.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

First time tying out business class with this airline, hat a disappointment, never returning. We didn’t get the meal as requested from Singapore to HKG flight. While meals served connecting flight, crew takes meal order based off passenger membership status by giving the. Priority selection of meals. It was a battle, plain disappointment, not worth the hype, price, class as categorized/ advertised

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

If my return flight was not so much better, I would have given an excellent review.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

The only personel that smiled at all were the flights attendants. Desk agents, lounge people none of them had a smile or even a hello. They were like dealing with dead fish. Again flight attendants were good. All other personnel looked like they didn’t want to be there or help.

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.

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

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

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

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

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

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!

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

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!

The to flight was excellent but the return flight the seats seemed not cushioning enough.

⭐ 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.
