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.

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

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!

Long delay, no gate agent at deplaning waited 15 mins at the gate. Baggage claim was wrong carousel and over 20 mins after arrival

Flight delayed Didn’t send second leg of trip itemerary First class was fair, but not great.

Nice to get moved from a middle seat to an aisle seat upon request, but why wasn’t I put in an aisle seat to begin with? The flight was not full.

They called me 2 hours before my original flight from SFO was to depart to let me know it was delayed and that I would miss my connection. They then rebooked on a different flight leaving a half hour earlier to a different connecting airport, so that I would not miss my connection. It all worked out and I arrived at my destination without a problem and 15 minutes earlier than the original flight would have. Nice!

Flight was delayed with no explication. There was ice falling out of vents on me.

Couldn’t order food for the family because all the good food was unavailable. We opted for bringing something on with us. I also didn’t like that I had to have T-mobile for online movies. Stupid.

Alaska is by far the best airline to fly with 😍

The flight crew home was so, so friendly and HILARIOUS. I’ll keep flying Alaska like I have for the last 30+ years!

Deboarding the plane was chaos. The passengers in the back of the plane started deplaning before the passengers in the middle of the plane could even retrieve their overhead bags. The staff of the plane did nothing to help.

Enforce the one bag rule for carry ons. Don't allow people to have 2 and 3 carry ons. Make baggage gets loaded onto the correct plane. My bag didn't get put onto my last flight so I didn't get it until the next day.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Crew helpful. Plenty of food although not great but ok. Good time.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Aircraft is designed with all 3 washrooms at the back of the plane, meaning that when there is service underway, there are no washrooms available and it gets very crowded at the back of the plane.

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

One crew member, Brandy was very helpful with recovering phone lost in customs. The plane was ancient and poorly maintained. Checked baggage did not arrive with flight. Almost missed flight because if insanely short layover time. Air Canada is worst flight I have ever booked with Kayak. Wanted to charge for headsets for on flight media.

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!
