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.

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.

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.

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.

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

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

The wifi was barely operable. just enough to charge me, not enough to be useful. I wasted 2 hours of time I could have been working. So now, I' have two hours of work this weekend to catch up on thanks to Delta's crappy technology. Plus I'm out the money!

It’s a 3 hour flight with no entertainment and no WiFi due to Delta using old planes on this route and food is cold. Today we were told no potable water on the flight to even make coffee or tea. Ridiculous service in this direct route for business travelers and non business travelers

Audio Visual Equipment lacking content and features. No connection ability for noise cancellation pods

All good except the dining. Both meals were the worst I’ve ever encountered on any previous flight.

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Nothing, it was a fraudulent transaction. You probably should have caught that.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Little communication with passengers after sitting over 1 hour for a maintenance issue Then we had to deplane- no crew communication Poor gate information after deplaned WiFi would not connect AT ALL

Hey as long as you bring me back to earth in one piece I’m good! Otherwise great flight smooth take off and landing good staff Only thing is the staff at the back of the aircraft chatters a lot it’s annoying at times but I’ll let that go because they are very sweet overall.

Wifi was good on the flight from DCA to Dallas and terrible on the flight from Dallas to Tucson. The forward head in the flight from Dallas to Tucson was putrid smelling entirely urine soaked. The flight from DCA to Dallas was delayed by almost 30 min with a plane change.

Checked in online. Seating map was inaccurate. Wound up in a middle seat. Couldn't download the boarding passes had to go to the counter to get them. Otherwise flight was ok.

With weather and severe delays it was disappointing we didn't receive any compensation for the 5 hour delay. Not even a food voucher.

The flight left without us even though we were on the ground in Dallas, and American Airlines wasn't helpful or available to rebook us on another flight.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Got home at 3am after deboarding the plane. No compensation offered by American

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.
