Pros: "NOTHING.........................................."
Cons: "EVERYTHING................................"

Pros: "Good boarding process, punctual,great cabin service"
Cons: "Baggage arrival"

Pros: "The evening meal was far better than the mystery cold cuts and drowned slaw on the daytime flight out of Hanoi. Crew were pro -- if a little terse at times. Pilot launched and landed the aircraft successfully, always a big plus in my books."
Cons: "Seat was hard and somewhat uncomfortable. I wanted bottomless refills of white wine but the stewardesses had other ideas. Pours were on the skimpy side, too. Passengers were fiddling with their damned devices during takeoff and landing, and the crew shoulda laid down the law there."

Pros: "The crew was very attentive and nice"
Cons: "The seats are very close together. It's hard to get comfortable"

Pros: "Great service"
Cons: "plane a little old"

Pros: "Good weather and a quick smooth flight"
Cons: "They kept shutting the lights off. The plane was very hot when we first boarded. In the air the air conditioner slowly began to cool off the plane."

Pros: "Priority boarding for pregnant passengers, leggy and clean"
Cons: "No personal service, meaning have to fill out the same waiver of liability every time we fly, even if flights are just a few days apart."

Pros: "Provided food for only a 3 hour flight"
Cons: "Boarding was a bit slow (still arrived on time)"

Pros: "Everything was good honestly"

Pros: "Everything! The service, friendliness, food, movies, clean restroom, etc."

Pros: "Staff were excellent. Plane was nice and clean. I would not hesitate to fly with then again."

Pros: "Food was nice and plane was clean and not too crowded."
Cons: "Before and during flight the plane released a gas into the seating area that made us feel sick, with a headache, and suddenly feeling very sleepy. Right after we got off the plane, we suddenly felt better. If we didn't get a sick feeling, the flight would have been good."

Pros: "Easy to change flight. Lots of leg room. Friendly service."

Pros: "The plane and food were good"
Cons: "Took a very long time to get checked bags"

Pros: "Great experience. Everyone very helpful."

Cons: "Our flight was scheduled to depart at 7:15 pm. We decided to grab a quick bite to eat before boarding. Our boarding pass indicated that boarding would begin at 6:45. They called "final boarding" at 6:35, just as we were wrapping up. I believe we were the last to board at about 6:35 or 6:40. Once we were on board the plane pulled away and departed a full half-hour before schedule. The early departure was welcome, but unexpected and made us feel more rushed than necessary without prior notice."

Pros: "For flying overseas the airplane was old and uncomfortable. I've flown overseas before and the seats have been a lot more comfy. The crew was fantastic and the food just crappy like any plane food."
Cons: "The seats and the food."

Cons: "There was no luggage requirment on my flight plan. I thought that it was 32 kg since it was international flight. At the counter I wad told I am over 20 kg allowed on that flight since this fligh was code shared with Vietnam Airlines but operated by Cambodia Angkor Airlines. After manager intervention my suitcase was accepted. I would appreciate clear communication about allowed suitcade weight on code shared flights."

Pros: "excellent ,no complaints. Good flight all around."

Pros: "The rolls were warm. That is literally the only positive thing I have to say."
Cons: "My first flight was canceled, which I wasn't alerted to until after I arrived at the airport. They booked me on another one leaving 2 hours later, which was delayed by about another 5 hours. I suppose it was the weather, but a flight going to the same destination on the same airline managed to take off on time, and it was supposed to be leaving 40 minutes after my second flight. I have a hard time believing it was the weather, but who knows? There were absolutely zero gatw agents there to offer any helpful information. They eventually gave us food vouchers, but it was about 5 minutes after 90 percent of the applicable restaurants closed. Everyone on the flight was forced to eat at dairy queen, which quickly ran out of everything anyone wanted. I will never fly Vietnam Airlines again."

Pros: "None."
Cons: "Flight attendants were not friendly and courteous. There was not enough blankets for every passengers. Food was a cold sandwich with water, juice or soda only, no alcohol available on the international flight. Overall, I would give this airline a "F" for failing to keep up with the standard of other airlines."

Pros: "Notifying customers of why flight was holding for over an hour in the air (due to heavy rain)."
Cons: "No food or drink offered during holding period..this more than doubled the flight time and was quite frustrating."

Cons: "Got stuck on the runway for a while"

Pros: "Everything was great in the flight. It felt fantastic to be treated like a princess."

Pros: "Look for other options if possible."

Cons: "I received at least 4 emails from Vietnam Airlines prior to my visit informing me of changes in our booking. All added time to our layover in either Hanoi or Ho Chi Minh on our return. Once we arrived in Hanoi we were informed of 2 more delays in our departure. I am traveling alone with 3 children all under 12 yrs &I make a concerted effort to book flight with the shortest layover possible. What would have been a 10hr door to door travel time turned into 16 hrs. Needless to say, I will not fly Vietnam Airlines by choice again."

Pros: "The service"
Cons: "It's a very short flight but the staff as always is very polite and welcoming"

Pros: "Good food on the 7:10 flight and everything was fine."

Cons: "Flight was delayed by 3.5 hours. 2 hour delay was acknowledged on the board when I arrived at the airport, but there was no communication after that time came and went. Flight did not begin to board until over an hour after the supposed delayed departure time."

Pros: "We left early, arrived early and had easy passage through the new Hanoi airport."

Pros: "They 1st change the gate from#1 to #5 due to flight is late arriving to the airport, then they have mechanical problem, after couple hours of repairs, the pilot has un-board the plane, then all luggage has been re-board to another backup plane. Then a bus took us to the plane. (back to gate #1 :) The flight is actually run by Cambodia Angkor Air (code share with Vietnam). We barely made our connection flight in HoChiMing City. The seats are cheaper look. They did offer a bottle of water for your drink."

Pros: "SGN-HAN Economy. The flight was uneventful, but I have a sad record of delayed flights. This one was perfectly on time: boarding early and in an orderly fashion, newspaper abundantly available. The crew was smiling and helpful, and served the meal early. This was a full meal for a 2 hours 10 min flights arriving shortly after 11:00 am! Ample knee-space. No entertainment on A321s. I would definitely recommend Vietnam Airlines for Hochiminh City to Hanoi flights."
Cons: "Nothing, really."

Pros: "Quick and easy boarding and very friendly crew"
Cons: "Nothing really. For a no-frills flight, it was a great value"

Pros: "Checking in goes well"
Cons: "after booking, air asia changed the flight schedule back teo hours. Then on travel day the flight was delayed another hour. So we arrived around midnight. Air Asia Is somewhat annoying as they’re always trying to sell you something during the flight"

Pros: "Nothing. It's cheap and really not because you pay for everything extra."
Cons: "Rude customer service. Baggage cost more than the flight."

Pros: "All"

Pros: "Our seats were comfortable and the landing was smooth"
Cons: "All food and drink had to be paid for -even water!"

Cons: "Food and beverages are not free. Even water cost money so you might as well bring your own. Also they advertised free WiFi but as soon as logged in you have to pay."

Cons: "this is the first international flight that charges you money for everything on board. hungry? purchase food. thirsty? pay for the water as well. even for the check-in luggage, you have to pay. so pay a little more and book a nicer-better airline. the crew is not professional and does not understand how to talk to clients properly. I am well aware of the fact that clients are often over demanding in the services they are being provided and rarely appreciative of the crew that does everything to make your journey pleasant. However on all the four Airasia flights from Delhi Kuala Lumpur Phuket, the overall attitude of the crew members was not nice."

Pros: "Good service, nice nasi lemak"
Cons: "None"

Cons: "I was charged $183 USD for the same bag that was free on Malaysian airlines. Huge extortion rip off."

Cons: "Baggage problems in transit"

Cons: "Luggage check-in weighs luggage 22 kilos more than its actual weight and I was asked to pay almost RM650 ~ ($170), when I was asked to recheck they had to pull my luggage back and that took almost 40 minutes to later know that they made a huge mistake! 20 minutes to the boarding time I got confirmation that my luggage weights are correct and given a boarding pass to gate P11. walked to gate P11 and saw no one there, and there were no signs of what was happening, I checked Kayak app then I noticed that they changed the gate to L10 which is a totally different building ( 16 minutes before gate closure ), I had to run the whole airport to go to gate L10. not to mention that flight was delayed by a good 1 hour!"

Pros: "Delayed 2 time"
Cons: "Everything"

Pros: "We arrived safe"
Cons: "Left large with no explanation. Uncomfortable. No entertainment or free food. I mean none"

Pros: "cheapness"
Cons: "weak maintenance and everything is chargeable including water"

Pros: "Inexpensive flight, attentive crew"

Pros: "The efficiency and professionalism of the crew."
Cons: "Nothing to dislike."

Cons: "Immigration offload for no reason then asked to rebook .."

Cons: "Notification of delayed flight wrong."

Cons: "They are very strict about the weight of your luggage and will not budge on the overage charge. They serve fish for breakfast...gross."

Pros: "fast and on time"

Pros: "Ease of checking in -- and getting to the gate."

Cons: "The short space between seats. Hard to get comfortable without room for knees. Have to pay extra for an aisle even if some are empty. Crew doesn't care."

Cons: "One hour delay on runway"

Pros: "Good flight"
Cons: "They don’t even offer water or drinks"

Pros: "Good music"
Cons: "A passenger suffered a seizure and the crew didn't know what to do. It was chaotic. Also, the pilot did not alert the passenger of potential turbulence."

Cons: "Flight was DELAYED twice. AK called it re-schedule, but with only 2 hours prior notification, it's purely DELAY. Poor coordination with airport, gate changed without proper notification."

Pros: "All except boarding"
Cons: "Flyers cutting que prior to boarding without intervention from air crew staffs."

Pros: "Nice clean plane and efficient staff"
Cons: "We Pre ordered (and paid for) meals when we booked our tickets, having flown Air Asia before we knew what was good and what wasn't. Somehow our orders were lost and we got the 'default' meal on all flights which was sweet and sour chicken meatballs which was almost as awful as it sounds. We heard the same thing happen to the lady in the seat behind us. Staff pretty much ignored our complaint. There's also a weird process with check in where you get processed into a small lounge Pre flight with no food or shops, there doesn't appear to be a reason for this other than making you sit somewhere cramped and uncomfortable for an hour before your 9 hour flight."

Pros: "There was a fee to change the automatically assigned middle seat to a window seat, but it was low: either $6 for a seat close to the front of the plane or $3 elsewhere. It was nice to have those options. First time flyer on Air Asia; I would choose them again."
Cons: "No beverage service unless you had booked it in advance."

Cons: "The flight was delayed today for half an hour"

Pros: "Nothing"
Cons: "Flight was delayed."

Pros: "Great overall economic airline to travel with considering the price paid. I am glad to have the options to NOT pay for the food and entertainment since I never used it during a flight less than 6 hours. I am sure the food and entertainment is good for many passengers paid for them. The flight is on time, the boarding is well organized, the crew is courteous and bathroom is clean."

Pros: "Low cost"
Cons: "We paid a small fortune for the couple of kilograms we were over our 15kg allowance."

Pros: "Arriving safe"
Cons: "Other passengers sneaking more than their carry on limit .Check in staff not allowing this.This caused delay of 30 mins to sort,holding every one up.This happens all the time with Airasia ."

Pros: "Value for money. Excellent service. On time arrival."

Pros: "Comfortable flight and friendly crew."
Cons: "Long check in lines at Siem Reap airport. High baggage fee (USD 36) for not having pre-booked a checked bag online."

Pros: "Surprised to see t&Co coffee is serve, good n keep it up Flight is early 20mins on reaching kl! Very good"

Pros: "We had 30 minutes delay for a passenger to clear the immigration issue."
Cons: "Nothing special."

Pros: "Staff, flight, seats, etc. were all good. We will fly Air Asia more in the future."
Cons: "Nothing to complain about. Everything went as seamless as a flight can be."

Pros: "There was nothing to like. Literally!"
Cons: "Delayed for more than 9 hours, which ruined a complete day of my trip. When inquired from local office, they were clueless and was really rude. We could not do the web checking as there was a error in the site and we ended up paying more than 3 times what we were supposed to pay for baggage."

Pros: "Great service and amazing food !"

Pros: "Flights were on time."
Cons: "All food and drinks were sold at additional cost, not even small snacks or water included in the price of the flight ticket."

Pros: "Nothing"
Cons: "All thing baaaaad"

Cons: "I was charged $94 canadian to check one bag that weighed in at 10kg. I honestly thought the man at the desk was joking. After that he sneered at me and suggested that if I had not booked through Kayak and instead through the airline, that it would be a little cheaper. He then pushed me to hand over my credit card so he could charge me. From then on all I have to say is that the planes have no entertainment, no leg room (they are known for the insanely tight seats) and no food. Not even a drop of water was offered unless you pay on board. Interesting...I wonder what they do then with all of the money they took to accept my one bag (it was seriously 10k, I'm a small girl travelling alone there was nothing large about it). All that to say, I wish I could get some money back, I would never have paid so much to check a bag if I had the opportunity to cancel the flight all together. I'm beyond unhappy with my experience."

Pros: "Good price - efficient transportation"
Cons: "Having to scramble to find money for water. I understand that it is a very well priced airlines but when you are stuck in a plane water would be nice to be free"

Pros: "Love the staff"
Cons: "Everything was expensive"

Cons: "I have flight from kualalumpur to Guangzhou ,there was no whight on tickets, I booked through Kayak web site , Only 15 kg per person is avaliable and for fees , At low fare , I have to pay twice my ticket price for I didnt book my whight before flight online ,. ? ? Flight was 4 hours to Gungzhou , no meals on board , not even a glass of water . You have to pay again on board for your food , and drinks , I feel like traviling in a low degree shattel bus , in a very very poor quality ."

Pros: "Clean plane"
Cons: "Charged for everything . We paid $1.50 USD for a small cup of tea."

Pros: "All god no food"
Cons: "No food"
