As the flight is a long-haul flight you should arrive at the airport 3 hours in advance and you can choose to make use of one of the many Business and VIP Lounges available to you. This is a good idea for some relaxation time and a good meal to prepare you for your onward journey.

The spa is found at the airport and offers essential wellness and relaxation services like massages, facials and much more.

The most popular airlines connecting visitors to Southeast Asia are Singapore Airlines, Etihad, Austrian Airlines, Malaysia Airlines and more. It all depends on your route and destination so click through KAYAK to find your best route.
  • If you are flying into Bangkok (BKK) and want to get a good night's rest after your long-haul flight there is a hotel at the airport grounds. The Novotel Bangkok Airport Hotel is connected to the airport terminal by a walkway and is easily accessible. You can also choose to use the hotel for a business meeting.
  • If you are flying from London into Kuala Lumpur International Airport (KUL), this is one of Southeast Asia’s busiest aviation hubs. After a long-haul flight you might need to relax and have a smoke, so you can luckily find designated smoking lounges at the Satellite Building located at the Mezzanine level 2, South Zone next to the China Air’s Lounge and North Zone next to Singapore Airlines Lounge.

one hour transit not good. cathay pacific is not helpful at all

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

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.

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.

Leg room wasn't that great. Other than that it was a good flight

Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?

A lot of things Never flying with this airline again Had an emergency landing

They downgraded me from premium economy to regular economy and me had 2 major lay over and had to have an emergency landing due to engine failure mid flight Don’t use them worst experience I have ever had still dealing with the trauma

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

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.

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 planes are very cold. The AC is too much.

It was great honestly the cabin crew were warm and welcoming everything was perfect the food was nice.

Didn’t like anything about the flight: I am so frustrated at this point. Since 8 days I have been dealing with your customer service regarding my seat changes. I paid $51.10 for extra legroom seats and one fine morning I get an email that my seats have been changed. I tried to contact the customer service and they have been just fooling me around stating that my issue will be resolved. Saudia is the worst airline. Pathetic. On the day of my travel, I came at the counter and the guy told me that my seat assigned is 36A and my wife’s seat is different. He then changed my seats to 33A which is not at all a extra legroom seats. I asked the person is these seats are extra legroom he said yes and when I came to the aircraft I am sitting in a normal seat. The TCR Shameer Ansari or Sameeri Ansari came and did nothing telling me that he tried his best find a solution. I need someone to contact me ASAP and I need a refund for the entire flight. I don’t need your Al Fursan points they are worthless. Contact me ASAP.

I recently flew with Saudi Arabian Airlines, and it was truly an outstanding experience from start to finish. The staff were exceptionally polite, professional, and attentive throughout the journey. Check-in was smooth and well-organized, and boarding was efficient and on time. The cabin was spotless and comfortable, with plenty of legroom and a calm, welcoming atmosphere. The in-flight service was top-notch — meals were delicious and offered with generous portions, and the crew made sure every passenger was well taken care of. I also appreciated the wide range of entertainment options, including movies, music, and TV shows in multiple languages. The flight was punctual, and the overall experience reflected the airline’s strong commitment to hospitality and passenger satisfaction. Without a doubt, I’d highly recommend Saudia to anyone traveling within the region or internationally. Their service quality easily matches — and often surpasses — many top global airlines. I’m looking forward to flying with them again! ⸻ Would you like me to tailor it for a specific flight route or class (e.g., Economy, Business, Jeddah–Washington DC)? I can make it sound even more personal or detailed.

It was a disaster. The crew was so rude and had no professionalism. She dropped something onto the floor, then took it from the floor and put it into the food tray. Also, when she got some spilling, she went straight to the toilet, got some tissue and started cleaning the food trolley

I cant wait for planes to have shorter rows with more space! otherwise, all fine thankyou

They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Damage lagguage, They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very 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.

Pillow and blanket are dirty. My son got multiple bites during the flight

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

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.

Food & service very good next I will pick up again

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!
