Airline reviews

The crew is amazing, very attentive. They went above and beyond when we had a small spill. the food on this trip was not nearly as good as other Cathay flights. The economy seats are very comfortable, but when the person in front of yo reclines, you need to recline to see your screen or be comfortable.

Cathay Pacific helps me with the planning due to weather delays. Well planed flights.

It as great, my in flight entertainment was malfunctioning though.

Flight crew went above and beyond to make sure the flight was enjoyable for us!

Both my husband and I ordered the fish for dinner and we both got sick and throwing up on the plane. I don’t think the seafood was handled properly and I for sure will not order fish the next time around.

Im now late to my appointment because of delayed flight

Dinner was served at the wrong time as soon as we boarded. Most were sleeping.. there was no food service carts for hours. We had to specifically ask for water, snacks etc. for the 15 hour plus flight, there should have been 3 meals served. Instead we only got the breakfast 1 hour before landing. Will try other airlines like Qatar for future travels.

I like the paper menu with lists of food, so that I don’t need worry about to pick up the food I don’t like, because crews are busy to do food service, mostly not enough food information they can tell. Well, one of the lady was not friendly at all, I asked three times my daughter wants a cup noodle during the flight, she gave me the reason is they have half an hour for serving food three times. There are more than 200 people on the flight, it takes them more than hour and half to do food serving, think about it, how long we can get food, around two hours. I don’t like she gave a stupid reason other than to make a cup noodle right away. Unfriendly and lazy.

The flight was delayed for half an hour, hope this can be better

Great experience, smooth checking, boarding and flight. Service during flight were great, crew members were very professional. Thank you!

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

No wheelchair service at all ( I did request that service and also purchased the priority assistant bundle) , what a waste of money

Never got the wheelchair service when my parents arrived at LA . My mom was 74 , also my dad was 84 years old, both don’t speak English. I double checked with the front desk at Phoenix airport, making sure that they will be taking care of.

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

I love flying Chinese airlines in general but China Southern is probably the worst of the lot. The service is poor and food is below par.

Flight canceled, but they didn't notify me. They arranged a nearby hotel and 4 meals for me to stay for 24 hours before I could board.

Had some luggage loading delays but it was still a good experience

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

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.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

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.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"

Our check-in was mediocre. We were told that we didnt have access to the lounge although we were in business and we were asked to remove 1kg from each of our checked luggages as they had 21 kgs and we found out that our tickets were for 20kgs checked bags. I would have expected: 1 - more clarity on the website so that I could see the difference on fares and be able to buy tickets with more checked luggage kgs allowance, and lounge access, and 2- more flexibility for business class passengers.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

It was a great experience. I did find that some menu options were not available, which was a bit surprising, but over all a wonderful experience.

I wasn't able to request a special meal on the on line check in. I informed the cabin crew and they went out of their way to find foods I could eat. I am very grateful.

All went well- allow plenty of time at Heathrow, we felt like we got bused halfway to chicago when it was time to board, then had to carry baggage up steps outside. A bit of work for anyone who is less mobile or able bodied for sure.

It was a pathetic experience. Booked Hindu vegetarian meal and they served chicken. Inspite of telling them repeated times, the issue was not resolved.

I never was able to take this cancelled flight…all flights from Zagreb were cancelled at 3:30 AM of departure day 9/8!

Experience was probably the best I’ve had on BA for a long time. Only thing is A380 is old now and it needs upgrading. The en re attainment screens are very small and the touchscreen barely works.

Flight cancelled! Rebooked by circuitous routing although there were seats available on other nonstop flights.

Service of the crews were great. Food on flight was very greasy, and salty.

Sardine can herringbone layout in business class. Uncomfortable and nowhere to put your book, phone, headphones, etc. worst hard product ever, and the service and food aren’t good enough to make it worthwhile. Expensive garbage. British Airways purchased this thinking only about financials, clearly not customer experience. British Airways business class is the garbage truck of the skies. Hard pass!

I never travelled better and more comfortably than with this flight because I was upgraded to the business class! it was amazing in every aspect. I was able to lay down and sleep, and the food was comparable to a gourmet restaurant menu. The flight was not only on time, but even much earlier, the crew was excellent as well. It felt like a very nice reward after so many uncomfortable and frustrating travels in the past decades. Even though most of my past trips were not with BA, they gave me a memorable gift with this favor. Thank you British Airways!
