The food and service was great. You have to pay a lot for in flight Internet though which is lame.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

The flight was delayed for 30 mins. The overall experience was good.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

It was okay overall but the food was very, very bad.

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.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

The plane interior was incredibly outdated. Nothing worked. My tray table was taped together (yes, TAPED!). None of the TV monitors worked. There were no buttons to turn on the overhead lights or call for a flight attendant. There was no indication of where we were or how long it would be till we got to our destination. This was a 15 hour flight btw. I was seated near the bathrooms and after a few hours on the flight, it smelled strongly of urine. It was sickening. There was only a USB charging outlet and you had to use your phone to watch movies through their WiFi. Somehow the outdated charger made it take so long to charge my devices. I paid for my seats and they definitely did a bait and switch on me. The seats I paid for were NOT the seats that I got. I will NEVER use this airline again and I highly recommend that others don't.

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar

Non reclining seats on a 14 hour flight. Crew skipped drinks for my row at least twice.

The planes are dated and need upgrades. Seats are not comfortable and entertainment equipment doesn’t work

First and the foremost I was shocked to see airindia standards have come down so low . The food was horrible . They served us 3 meals for vegetarian and all the was paneer . The orange juice was not at all cold it was smelly . After you take this heavy price air India should learn from other air lines . I at one point felt like throwing up . After all this when we landed we were not given landing slip . We had to wait for 45 min at the immigration just because no one was given landing slip . To top it all we were 3 passengers and had checked in 4 check in luggage . Out of which 3 have not yet arrived . Basically status says the loaded it in our flight ( this was a direct fight ) and it never reached . We are still waiting . There is nothing great to tell about our flight . The he only good thing was the crew were very helpful .

Bags got damaged for multiple passengers, and they wouldn't even reimburse the depreciated price of the bag.
