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.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

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.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

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 am a United 1K flyer but certainly I would fly ANA again. Great inflight service!

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

Great. Very helpful staff and accommodating. The flight was also smooth

My son flew and had a great experience.. thank you for taking care of my baby

The flights with ANA were great. The flights with United, not so much.

I enjoyed the flight, but a little too much turbulence on the flight. Thank you for the meal and entertainment. This kept my kids entertain during the flight. I have to admit comparing the crew from ANA vs United, there was a sense of more accomodation, friendliness and service compared to United crew. I felt for the United crew, it was just a job and it can be seen in there demeanor and delivery.

Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.

I loved everything about my experience!!! The staff were absolutely incredible. I can not wait to fly again with them.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

we were in premium economy, but we both got middle seats and had to sit separately. i could have avoided this by trying to obtain seats sooner, but i tried 3 times and gave up. ANA's technology is not friendly for newcomers. no, check that---I think it is nigh impossible. not sure we are coming back. ana can do better to provide a front end that's friendly to users in both US and Japan.

Good service. I wish there was more legroom. The food could be improved with additional options.

The crew was very attentive and delivered great service unlike any other airline. It was our first time with Emirates. Our only critique is the food. Pasta pesto is not very common. Tomato sauce would’ve been more of a crowd pleaser. Beef curry sounds bad because curry can be very tough on the stomach. We were in row 26 and the pasta ran out, meaning no one wanted the beef which says something. The beef was just ok… The rest of the food was very good and generous. The plane speaker sound could be better. It was tough to understand announcements even with headphones. Although we did not need them this time due to the purpose of our trip, we were surprised that 2 checked bags were included. That’d be great for the future. It was unpleasant though that our personal items were weighed (we’ve never had another airline do this), especially when we didn’t have checked bags and almost had our carry-ons checked. Overall it was a good experience, but we wish the prices were friendlier for such a short distance (Miami > Colombia).

It was very exlent flight and thanks a lot kayak

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

I love to travel again and again in Emirates. Keep up the good work.

The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

I wish any of the US airlines operated like Emirates

Better information about the delay due to screening for US

Flight was delayed at airport with large backlog and WiFi was spotty

Really hard to tell what was happening after my flight got delayed five times

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

Flight was warm for first few hours and quite rough

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

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

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

great starting with the business Class that's was Amazing . thank you United Airlines and brussels Airlines

Best flight in years. Pre-boarding because of my mobility issues. Good food and beverage from beginning to end. Excellent choice of films. Good service by stewardesses. Comfortable seats. I could lie down!

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Bad check in experience. Dirty ancient aircraft. Truly awful food and this in Business/ First class.
