Tengku kamal asriFlew with Thai Airways-Aug 2026
Be at the airport early as you know the airport is so big
puraviFlew with Bangkok Airways-Jan 2026
Krabi is a small but very efficient airport. Check in kiosks are readily available. Bag drop had a line but it moved quickly
DavidFlew with Thai Lion Air-Jun 2025
Avoid Air Asia, rude staff and they act entitled and make you feel they are doing you a favour and not treating you like a customer.
Verified travelerFlew with Thai Airways-Feb 2025
Get to your gates early, to make sure you are understanding what is being said sometimes the translations are not clear. Not their faults I’m in their country, I should learn more Thai :)
Verified travelerFlew with Singapore Airlines-Nov 2024
Be there early LONG LINES. If you want to experience the JEWEL At Singapore make sure u have a 6hr min layover. I suggest you get a locker for luggage. You do have to leave the airport and go thru immigration on your way out and back in. The lines are long.
Verified travelerFlew with Thai AirAsia-Jul 2024
Low cost airline have sometime what maight appear awkward travel times however choose well and you will infact gain time in you destination.. DMK is still totally fine and you get much cheaper flight choices
TananyaFlew with Malaysia Airlines-Jul 2024
Malaysian Airlines is a good option. They don't have a screen but you can connect to onboard wifi and watch onboard entertainment, movies, and music on your smartphone or tablet. Bring your headphones. Some people didn't put on headphones and disturbed others with the sound from their phones.
JaniqueFlew with Thai Lion Air-Mar 2024
If you have more than 10 kg of luggage , buy the extra fees online because you will be charged three times more at the airport
GordonFlew with Bangkok Airways-Apr 2024
Try to put all your stuff in your checked luggage and take a light carry on.
JoshuaFlew with Bangkok Airways-Mar 2024
insist that the person checking you in checks you in all the way though. Do not leave until you have all your boarding passes
Verified travelerFlew with Thai Vietjet Air-Jan 2024
Look for food/ water in the airport as none is available on the plane unless you have made specific arrangements with the airline.
Verified travelerFlew with Thai Vietjet Air-Dec 2023
Go to the gantry early as more time required for transfer to aircraft

The flight left on time and landed early. The attendants were polite and friendly. Thank you

Efficient and fast check in, courteous staff at counter and on board. On time departure and arrival. AIR ASIA is my favorite international thailand carrier for reasonable cost and excellent customer service!

Delayed us three times, changed gates twice, and then tried to charge for food on the plane.

Air Asia just dreadfull. Always poorest customer service and very unwelcoming staff which is clearly bread in from the Top down from the CEO

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Very good, it would be good if payment for drinks could be accepted by card too.

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

Direct flight to BALI was good and convenient. Improvement suggestions - provide complimentary water

50 minutes delay on boarding,but overall delay time almost 2 hours on arrival.

I specifically searched for flight with checkin bags. Airfare assist website still sold tickets without check in bags and I had to pay 3 times more for my bad. Worst experience ever with untrained staff and haphazard boarding

As a frequent flyer, I was impressed with the smooth take off.

No frills means no frills... I just got on the plane and flew. That's all. Nothing more and nothing less. Or I did buy some water, they took cash only! LOL

First the flight delayed 1 hour ND then when we suppose to landing the pilot decided not to land at the chiang Mai Airport but the chiang rai airport

I liked that we got to our destination safely. I did not like the “no” amenities. The plane was very cold and a blanket was only offered for sale. In fact the only things you could get were for sale. Food, water, snack, etc. I’m very surprised that they did not charge to use the lavatory. The seats were uncomfortable and did not adjust. My butt literally hurt after just a 4 hour flight. I don’t remember the cost of the flight, but more than $10 was not worth it. I’ll never fly Cebu airlines again. Ever!

The seats were dirty. Food on tray table. Late on my first flight and almost an hour early on the return. My driver was unable to adjust and I had to pay for different ground transportation.

No entertainment and not expected. Cabin was very cold which brought the comfort score down

I was memorable! THIS FLIGHT WAS ALL ABOUT WAITING! WAITING TO BOARD SINCE FLIGHT WAS DELAYED. WAITING IN THE RUNWAYS NO AVAILABLE PARKING BAY. FOR THE LAST TIME WAITING FOR FOOD COMPENSATION

Can buy food instead of online order. Maybe limit the meal so no waste.

Terrible, I will never ever ever attempt to fly on Cebu Pacific. I understand that it’s a cheap flight option but they take cheap experience to the next level.

better handling of the checked in luggage. they destroyed mine

Should’ve not separated those who checked-in online and those who checked-in at the airport

Was denied early boarding for a hot seat row 1C. I asked gate attendant why I couldn’t I board as I paid extra for that seat and it’s privileges that come from purchasing it. and she said no that Cebu Pacific does not allow it. When I boarded plane finally I had nowhere to put my bag as the seats behind me had taken my overhead area. The flight attendant said that the gate attendant was wrong. I fly a lot in the philippines and to Japan and now I have no choice but to fly with Air Asia. At least they board with zones and allow rows 1-3 to board early.

Poor service in Bangkok. Flight attendant is not friendly. You have to buy everything like water and coffee. Expecting for International should have free food or free snacks.

I rated the experience poor because I had to purchase new tickets to return to Phuket because the airline had no record of my flight.

i think allowing passenger to have personal handbags or bags in their lap is a safety issue. As for food there was not onbpard and had no other choice. We also waited for over 1hour 10 min for some reason and keep getting we will be departing soon.

Newer plane and comfortable. No wifi and thier website and App. are horrible. Tried to purchase luggage online and could not do it.

I don't like this airline. The website is not user friendly. I tried to check in multiple times and no joy. Then I googled why might this airline not let me check in and it said if you are checking baggage you can't check in. I really thought that I had purchased baggage. Because I have been traveling for 3 months and making sure that I pay for baggage on every flight. This flight they said that I had not purchased baggage but there is really no way to check on the passenger side.

I wasn't able to check in. The website could find my reservation but then an error occurred. I tried 4 times spread out through the day and got the error message every time.

well it was a short flight so there was no food but couldnt answer that question with a N/A There was no entertainment so N/A but the flight was great and staff was number #1

Never on time when I fly and Thai Vietjet App is too complicated. I had booked und paid for seat number 15A but when checked in, I got another seat number and row. I paid extra 50 bath for what??? They couldn’t change and I got no refund. No time to discuss with the ground crew to change it. I would never pay for seat anymore.

Excellent experience nothing could be improved with staff. Was hoping someday the airline will use tape recorded lfor languages that are not common to staff. Probably with AI it might be a good addition

We were packed in like sardines. They did not even serve water on the flight!

Everything was good just the part on the need to transfer via bus to plane

Everything were ok except that if we wanted to drink even a glass of water in the plane we had to pay !!

Great from start to finish. Staff very friendly. Flight smooth and comfortable.

Delay of 3 hrs and they offered only Macdonalds pineapple pays. Not any good

The return flight was delayed for more than 4 hours. Luckily we were in the airport way in advance and managed to reach out to the Nok Air sales office to squeeze us into the earlier flight.

Lead flight attendant was rude and not helpful. Very unprofessional.

Purchased additional baggage and the flight was canceled due to covid. When they rebooked us they didn’t carry over the extra baggage. They wanted to charge 3x the original ticket price for “added” weight… 6000 bhat for an additional 15kilo (which would of been easily covered by what we originally booked) took nearly 2 hours to work out and they only let us check in minutes before our flight boarded. Very unhappy.
