Plane took off on time and I had the whole row to myself!

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.

This flight was a superior flight in all regards. Extremely pleasant experience.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

Check in process was terrible. Lady at counter didn’t know what she was doing

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

The crew was amazing; Von, Vera and Guadalupe were very friendly and attentive throughout the entire flight. They were friendly and welcoming to everyone. A solid and dedicated team for sure!

Terrible. I was bumped off of my original flight and spent the next six days fighting to get back on it. I lost hours of my vacation trying to get this situation corrected.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Ok. Get a different kosher caterer. The food was odd.

Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Lost luggage, they need a baggage service representative available all times in Atlanta

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

My return flight experience was one of the worst times I have had traveling anywhere this year. Not because of the flight. It was because there was not enough time allocated to deplane, go through U.S. Customs and U.S. Security to get to the gate for the connecting flight to Boston which I missed, There was well less than an hour between my landing in Montreal from Prince Edward Island to my connecting gate. I even called Air Canada on the morning of my return and noted my concern over the short layover time, not more that 45 minutes. The initial flight was four minutes late. I was seated in the rear of the first aircraft, and it took at least 20 minutes to deplane. The U.S. Customs was a considerable distance from the gate at which we landed. The need for double security seemed unnecessary and redundant. The distance from the security to my gate was again fairly great, and the wrong gate number was listed on my boarding pass. The agent I approached at the flight that was going to Newark, New Jersey was too busy to answer my question as to what gate was for Boston. When I got to the right gate, they had just closed the door to the aircraft even though I arrived a minute late. If I knew the distance to Customs and from Security to the gate, I would have asked for a seat on the next available flight which was 4:30 pm. When I made my call at 6:00AM that morning. When I asked the agent at the Boston gate, he said that the 4:30 flight was already “OVERBOOKED!” I was put on an 8:30 PM flight and didn’t get home until MIDNIGHT. I then had to care for a barnful of hungry animals and didn’t get to bed until 2:00 AM.

From Montreal to Cincinnati the flight was perfect! Flight free and everyone was perfect and a pleasure to travel with. But from Casablanca to Montreal the flight crew were quite cold, unhelpful, also seemed to scold many passengers instead of simply educating or instructing them. There were a couple for sure I could describe but not name… i was really shocked bc my experience w air Canada is typically a good one at the very least. It seemed something was very much so I’m the air w the crew. The two older lady crew members and the male were amazing but the younger lady crew members w the exception of one were very clique-y and snarky, sassy

Seating wasn’t too cramped; I don’t understand how luggage bins get full if there are enough for each person. Shouldn’t there be room for the designated carry-on and personal item for each passenger at their seat? THEN, IF for some reason extra room is available for someone who prefers it, then shifts can occur. I’m simply saying it seems that I should have primary access to the storage bin at my seat and underneath in front of me. It was suggested that I go to the back of the plane to store my carry-on when I paid to have access to the first seat after 1st class. The additional stress and inconvenience could be avoided and I think all passengers and flight crew are interested in guidelines that are fair, clear, and reduce tension.

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.

Orlando to Canada, despite being close and an international flight, the plane was not at all comfortable. It felt like the chair was being pushed forward, in addition to not having a TV and having to choose from a tiny glass of drink, for example, water or soda. I couldn't have both. When I asked the flight attendant for an extra glass of water, she looked at me with an ugly face. This is ridiculous. They don't want to give water to passengers. I will never fly with this airline again in my life.
