Milan airport was bad experience. They should be more polite.

Food was great. More vegetarian options on menu would be great!

Child’s meal was great along with other nice touches for kids.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

Premium economy was worth it-comfort was definitely better than economy class. The seats were more comfortable, blankets and pillows thicker

Very poor boarding experience with these remote gates and buses. Also these 777s bardy need a remodeling. Entertainment is a bit laggy. Food and crew is still among the better, but they seriously have to do something with these remote gates.

I take emirates because of direct flights Otherwise no Cabin crew niot friendly and never friendly across the airlines Planes old inside not renewd .. this is not an issue The issue is the poor service

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Crew were very good. Food service was a little slow and disappointing not having on demand dining and only 3 options. Amenity kits and pyjamas were excellent.

I had a good experience flying with Emirates. All of the flights were on time staff was very professional and kind. So I had a positive experience..

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

This is a very short commuter flight, so there is no food or flight entertainment. Hence, I marked it in the neutral flight left on time. The plane was full pretty much and it was a pretty easy flight overall very good.

The flight crew and attendants are very professional and polite.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

For a domestic flight, seats are ok, but fir us as tall dutchies, the legroom is too small. However, for a short and affordable flight, is not a big problem. Staff is still very nice and a complementary water very welcome.

2 hours delay, time changes started already 2 days before the flight

Average, not more then that. Cannot compete with Singapore Airlines

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

Good. It would be great if comfort seats were available

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

I was denied boarding at the Brisbane airport and it seems like I won’t get any refunds from the airline

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

Overall I had good experience with China Southern airline. Nothing to claim. I hoped they could improve the meal quality that is.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.
