Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

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

I wear hearing aids in both ears the infotainment system is hard to hear.

I was mid plane and they were already out of the main beef entree....ugh!

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

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.

Really BAD check in experience. My bag was left in Geneva and I have not received it yet. I have been in Stockholm 5 days without clothes to change. The flight was good but very unhappy with the post service support.

Water bottles could be in more sustainable packaging than plastic bottles

They lost my luggage on December 30th. It is now January 3rd and i still don’t have it. I’ve called lost and found multiple times and they cannot provide an update. They keep saying one day and then it gets postponed again. This is ridiculous and unprofessional. It’s infringing on my vacation. I have stressed how important it is for me to have my suitcase right away. It should have been resolved within 1-2 days.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

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.

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

The flight did not take place because the flight was canceled and I still have not received a refund for the flight.

Not good. We returned on united airlines and the food was horrible.

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

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.

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

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

United lost my travel information and canceled my original flight. I had a seat assignment but was refused the booking. I had to prove that I went to Germany on United Very concerned about security that no one recorded my passport from Cleveland to NY and NY to Frankfurt I arrived at home at 12:30am on Saturday instead of 8pm I expect a full refund from United Please provide information to assure compensation

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

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.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Took a long time to board. A long wait at the but taking us to the plain

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

I wouldn't recommend Lufthansa otherwise. We took this flight only because our flight to Kittilä got cancelled and Lufthansa offered a replacement which would have been two days later, with a night in Frankfurt and another in Munich. We refused the replacement but the staff at the airport entered in the system claiming that we accepted the replacement.. We didn't get the full refund because of this.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Limited entertainment. Music - very limited variety of music. Suggest more options in Hindi, Telugu, English for flights leaving from Hyderabad.

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Food was good. For a long haul flight, there was “0” zero entertainment! What a disappointment. I do try to avoid BA. Next time its Emirates via Dubai to Cairo.

The internet was working on both sectors of the flight so hard to take the flight if you are on business.

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.

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).

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.
