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
TomFlew with Asiana Airlines-Jul 2024
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.

Automated check in could have been better organised and informative

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

As usual, poor communication on delays. No info, no updates, no apologies.

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

should remind people who cough must wear the mask. A few persons surrounding keep coughing.

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

Bad experience, delay like no tomorrow. Original schedule departure time at 9:30pm, delayed until 12:05am only depart.

Crews could have been more friendly and helpful . One specific crew was a bit rude to some passengers

I regret flying air Asia everytime I fly them. Baggage policy is a joke and the fact they issue mobile boarding passes but you can’t ever use them?? A waste of everyone’s time (you can only use them flying out of bangkok or KL)

I don’t travel I need my ticket back until now am with so many communication daily to get my refund
