Reviews of the top 5 airlines flying from Incheon Intl to Southeast Asia
Very long flight time. Still better than a connection flight. Staff is very good at service. Vegetarian food is not very good.
Very long flight time. Still better than a connection flight. Staff is very good at service. Vegetarian food is not very good.
The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.
Lousy entertainment system. Crews are excellent. Meal is just mediocre.
Great service and comfort level. You can have more of vegetarian food options.
It’s great, long flight and arrive safe at destination
Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.
I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.
There could have been better spacing of the passengers, it was crowded in some parts of the plane then other while rows were empty
Plane took off on time and I had the whole row to myself!
One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.
Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available
Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.
Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.
I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.
plus: service and personal assistance minus: online check-in did not work
All in all the flight was good. Love the fact that for airline food it was piping hot
Would have been nice to have more variety and less dairy in the Indian Vegetarian special meal. Why do they include Parathas as part of the entree and also on the side (substitute for bread/roll)? Also, no need for so much dairy...don't need milk packet, yogurt and Chobani Greek yogurt in the same meal.
Always on time. Clean and good service as always..great food too..thank you SQ, the best airline in the world👍👍👍
Please have the artiste showcase of classic international movies. Please have better food. There was no dessert or yogurt in my Ind Veg meal.
Very good customer services before, & during flight. I will choose it again in the future.
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.
Amazing experience, tonnes of leg room, great crew and smooth flight. Especially for this price for business class.
Great Value with Tway Airlines I highly recommend flying with Tway Airlines—especially if you're looking for a budget-friendly option. While the lowest fare comes with limited luggage allowance, it suited me perfectly since I was traveling light. Check-in and boarding were impressively fast and hassle-free. The ground staff and cabin crew were exceptionally polite and courteous throughout the journey. Although the aircraft was an older model and lacked inflight entertainment, this was a minor trade-off considering the ticket cost was nearly 70% lower than typical fares on the ICN–FRA route. If you're focused on value and efficiency over luxury, Tway delivers a smooth and pleasant experience.
I liked cleanliness, comfort, kind staff. I thought communication about meals could be better. We did not know how we were supposed to ensure we had food and drinks in our booking
ok flight, but charged for everything. water, food, baggage. no free water available, I had to plead to give me water to take medicine.
Need to consider about zero entertainment services and lack of flight information!
I can't board the 2nd flight due to the last 1st flight. In the 1st flight check-in, I can't board due to the stupid problem of K-ETA visa. The booking system and the flight company should inform the customer a few days earlier. This is the worse experience in my life. I won't use KAYAK and the airline anymore. My friends were also surprised about this stupid situation. I won't use KAYAK and T'way anymore.
I can't board the flight due to the K-ETA problem. You should inform the customer clearly a few days before the flight. I can't cancel/change the flight now. This is the worst experience in my life. I also never hear about this kind of bad experience. I won't use the booking system and the flight company anymore.
For a low cost airline they provide excellent value and modern planes. It did not feel cheap. But onboard drinks and meals are expensive and do not offer great value. Overall, a good experience.
“They carefully called each boarding group in turn, only to herd everyone onto a bus for the drive across the airport apron. By the time we reached the aircraft, all semblance of orderly boarding had disappeared and it became a complete bun fight to get on board. Rather nonsensical really — why bother with boarding groups in the first place?”unless you are at an air bridge!!!
Forthright communication to the customers regarding services offered and any fees involved.
I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.
Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.
The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable
We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT
We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.
Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.
Me and my Partner were in seats 6A and 6B. (Which we paid a premium for). Unfortunately the person is seat 6C was large and because of his size my Partner was squashed to the point of discomfort and unable to sit properly. We requested to be moved to some empty seats and two hours into the flight the crew moved us. Perhaps it’s time airlines began checking passenger sizes to ensure they don’t encroach into fellow passengers seating space!
