It was just a short flight. The crew was nice. No major issue.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.

JOKE of a company with the most Ridiculous policies. JAL is amazing, KAYAK/UNDERPRICER is the worst company I have ever dealt with, NEVER AGAIN

Absolutely WORST experience I’ve ever hard NEVER buy your airline ticket through a third party website, especially this one. Basically stole $1300 from me and has the WORST policy taking a WEEK to change a name on the reservation? A complete joke of a company.

There was a problem with the maintenance so missed the flight from las vegas to L.A and then L.A to Narita with japan airlines. They took care of the problem by rebooked with cathay pacific airways.

Horrible like always, flight was supposed to be at 11:40am, we ended up getting a different airplane at 3:25pm.

Overall, a solid flight experience. Boarding was quick and efficient, even with a full and overbooked flight. The flight crew did a great job providing attentive and friendly service throughout. I flew in economy, and while the seats were acceptable, they could definitely use more cushioning, especially for a 14-hour flight. By the end, it was quite uncomfortable to remain seated. Legroom was also limited, particularly with a bag stored under the seat and the passenger in front reclining. That said, everything else went smoothly, and I appreciated the professionalism of the crew.

The flight was delightful overall. The check-in and boarding were on smooth and on time. Amenities and staffs were elevated. However, if glasses were served instead of cups, there should be a complete premium.

Sure I would’ve liked a little more space, but it was better than economy. I bring my own food because I have food allergies it would be nice if they offered larger salads or more vegetables instead of starch it was really a good flight. I don’t wanna complain. I’m grateful to fly at all safely. Thank you to the pilots.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.

Planes were clean, no water or snacks on either flight.

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Lost of requested seat assignments. Lost my husband's meal choice

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth
