Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Extensive delays, poor organization to board people, as it felt like chaos to get inside of the plane. No lines, everyone gathering together like a mayhem, very confusing. Passengers out of hand and rude, which is not the airlines fault. However, there should be rules, e.g., not letting one passenger take 2+ spots in the overhead bin.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

Food , drink experience were great with Cathay. Crew service was excellent. Clean toilet and full snack bars always, pilot took of 26minutes later when boarding at Hong Kong with extra US customs check at gate 9 for US flight, but he managed to arrive only 2 minutes later from flight tracker. Smooth flight .

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

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.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers. A BIG ISSUE FOR NON-CHINESE PASSENGERS IS THE ABILITY TO CHECK IN ONLINE, by making so difficult or almost impossible there is no chance to get a seat assignment ahead of time then go to the airport and get what is left. THIS IS NOT a SKY TEAM modality.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers.

2 parts to the journey. First leg covered in a newer plane with decent staff + POOR FOOD QUALITY but the second half didn’t leave a positive impression at all as the plane itself was an older built and the crew didn’t serve properly. Language is an issue with China Eastern flights as always, but unmotivated crew just makes it even bad.

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.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

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.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

boarding and flight very smooth. Crew very friendly and efficiant. Everything worked well

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

Hate their old flights, boatding, food and services. Very poor quality

Horrible seats. They were just coach seats with the middle seat blocked with a dirty seat tray.

Comment for Lufthansa is just perfect, similar to my first flight comment.

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

The issue was not with BA it was with the link yoiu sent fopr booking the flight

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

BA flight from London NY had old BC configuration with 2+3+2 seating with open seats which was not comfortable and lacked privacy

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.

We got delayed for 3 hours and. Missed the connection. This is the 3rd time this happened with this airline

Staff except one has poor attitude. No cabin crew seen for several hours during the flight in business class. It felt like I was traveling in economy Drinks bad in business class Flight was late for no obvious reasen and I missed my flight to Miami I was put in a 3 star hotel in London although I was traveling in business class. Dinner was aweful at the hotel Overall very poor experience
