The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

Ford not that great the seat not to big for leg room like other airline

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

The boarding experience was as expected and went well. The plane's economy seating plan is not designed for a positive customer experience but rather for company profit. When the passenger in front of me reclined, the distance from the screen to my face was the span of my hand (thumb tip to pinky fingertip). There is no such thing as personal space in this setting. This results in the domino effect, for when I recline the person in back of me reclines and so it goes. This is not to say that reclining is the answer as the experience is not increased, but simply managed.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

Lounge in pukhet not good Very nice new aircraft Super crew as nearly always with Cathay

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

We requested special assistance and Cathay Pacific provided it in Sydney, but we were completely forgotten about in Hong Kong - when we really needed the help to catch our connecting flight. Really disappointing service.

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

It was okay, no wifi or entertainment real disappointment. Staff onboard not very friendly.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.
