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!

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

My business class seat was inoperable and unable to recline for 10 hour flight.

Flight attendants were ok. But it was a full flight.

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

Flight and attendance were very good we had 2 hour delay that took the shine of it

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.
