Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Food choice could be better, plus the crew can walk around and offer snacks and drinks. Also the air-conditioning onboard blows high speed, and very cold makes the trip uncomfortable.

long flights are difficult but the crew and amenities made it a very good experience

Always have great flight experience on Korean Air. Glad to have been able to book this on Kayak/Under Pricer this year!!

An International flight from Cebu to Incheon was delayed the night before without a proper explanation. Same thing happened from Incheon to Cebu in the first leg. I will not fly Korean again. And I will ensure Delta their US partner hears about it. This is a routine by Korean to delay flights from and to Cebu via Incheon.

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

The food is always good and that flight was particularly good.

Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

Absolutely wonderful,love the big clean plane specially the good food.

Was an easy and great flight. On time. Food was tasty and the only complaint I have is something no one could do anything about. Seems like there’s a lot of ill people in Korea these days and the flight was full of people coughing.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

The trip was very smooth and they provided great customer service

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

it was red eye flight, it was ok, there was beverage service, thats it i didnt care much as i wanted to sleep

There wasn't much leg-room, and although I requested a vegetarian meal, there was an error and I did not get one. Everything else was excellent.

1. Nowhere to sit at the gate D4 2. No control of lining up in different zones 3. People pushing in during the line up of zones. 4. Certainly not in a dignified manner.

Everything went smoothly. I appreciate the selection of free movies.

I like the friendliness of the crew members. I think the snack could’ve been better instead of a small package of pretzel. I like that they offer me something to drink.

The TSA agents in Phoenix were incredibly rude and confiscated belongings that we wanted to check. The flight got changed without our knowledge to a worse situation. The whole thing was terrible

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

My experience with Air Canada was good. Great customer service… only a few delays and issues with the tunnel to exit the plain. I did not appreciate that we arrived at terminal D and had to go to terminal E to get the bags/ luggage.

PDX staff was great and we arrived on time in YVR.

They announced before boarding that the flight was full and there would be limited space in the overhead bins and you could check in for free. We did and after we boarded the plane found it was not full and there was plenty of space in the overhead bins. I’m not sure why they made this announcement.
