You have to prepare for the waiting time for immigration to Vietnam, it takes 3 hrs to go thru and it is easy to get mad of it

We spent our long layover in the transit hotel in terminal 1 of Incheon Airport. The room was small, but was also very clean and well kept. I'd highly recommend this hotel if you have a long layover. The price wasn't bad at all.

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Friendly staff but otherwise a typical no frills airline. The sets are extremely cramped

Flight delayed for one hour last minute change the gate this is something new? Wak all over the airport bit fast bording to flight smd miss my meeting in kuaa lumpur is the year end meeting no internet in flught which is not good Anyway overall is good thanks to the crew on duty Un able to check in on line and choose the seat thatbi wanted and in flight meal too unable to purchase rrally sad Should get priority seat in next booking

We recently flew with AirAsia and encountered several issues. Our flight was delayed by over an hour, and both boarding and takeoff were postponed without any prior notification. Although we eventually realized there was a delay on our own, the crew did inform us afterward. To make up for lost time, the pilot took off at high speed, resulting in some turbulent moments that were quite scary. Despite these challenges, the cabin crew did an excellent job managing the situation and easing the inconvenience. Overall, while the delays and turbulence made for a stressful experience, I appreciated the crew’s efforts to keep us as comfortable as possible.

It was good. The FACE check in at KLIA2 was not working.

The flight delay... but bus from the airport be on time

Great. Very satisfied with a direct flight from Penang back to HK international. Stewards in the cabin were very friendly and helpful. Would not hesitate to fly with Air Asia in the future.

No complaints. Made it on time with a minimum of hassle. Some complementary soft drinks would have been nice tho.

Actually my flight from Hing Kong to Kuala Lumpe has been cancelled and I don’t see the refund of my airfare. Thats my comment of your Company and please follow up。

The crew is good, but the flight delayed and there is two passengers keep talking during the flight

100% dislike due to last minutes flight cancellations and terrible customer service experience. Do notice us early at least 24 hours before departure time.
