Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

Really good! I like all the crew, they were so nice and very efficient.

Food tasted pretty good. Boarding was very smooth and efficient, compared to all other airlines I’ve been on. I have flown EVA, Cathay, Asiana, British Airways, and many USA brands. Cabin attendants were also efficient and professional.

My flight with Korean Air went quite well, I've flown with them for many years and have grown accustomed to their great service.

Overall, very uneventful and pleasant experience. Most importantly, no delays.

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

6 hour delay including one after we were boarded. Horrible experience.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Everything was Okay. I was disappointed our luggage didn’t arrive with us and came in a flight 7 hours later. Representative said the will be delivered to the hotel. They have not arrived 24 hours later

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

Food TERRIBLE! In First Class- so bad - why was it so much better 20-30 years ago? Comfort-awful-would rather have the old, plush First Class seats than the new hard - too short seats in the new pods -would advise avoiding Delta for any International Flights.

7 hour delay for mechanical reasons Handled badly by crew and delta personnel

In thirty years of traveling, mostly with Delta, this was the worst day ever.

Would have liked better movie selection, but was great overall.

Jet Blue lost my bags after charging me to connect with HAL.

The partner Jet Blue in DCA connected me to BOS. They charged me $140 for one bag, despite the fact I’m Pualani Platinum, and bought the ticket on one reservation through HAL with my Bank of Hawaii HAL credit card, and the ticket was first class, full revenue ticket. To make matters worse, Jet Blue didn't process my luggage through in BOS, missing the connection and I arrived in HNL with no baggage. When I spoke to to HAL staff, they said nothing they could do with any of this, I was on my own to figure out.

Extremely frustrated that I followed all directions and Hawaiian Airlines made me leave my surfboard at the airport and refused to let me check it.

Board the planes first class first then the back to the front! And when getting off should be first class and front to back. Food is awful

KAL Business Class was old seats on an old plane. Service and food were good. Connection at ICN was a slow nightmare from Terminal 2 to Terminal 1. Long walks. Long train ride. Few moving walkways. Carpets hard to pull rollerbags. Literally 90 minutes from landing to long walks to long security line to more walks to departure gate. Hawaiians lists Asiana Business Class Lounge, but NO LOUNGE, that relationship is over (but still listed on Hawaiian site). Couldn’t get seat assignment on Hawaiian flight boarding pass until reaching ICN.

Almost everything was perfecto expect for entertainment. There are not a many options.

The screen where I sat was not working and charger also poorly. Can’t enjoy entertainments and space of seat was narrow.

The Hawaiian airlines checkin desk was too small for the number of checkins. The seat on the plane was right next to the jet engine and it was very loud. It was probably 90 decibels or more loud. They should offer protective ear muffs for those seats. Seriosly. It was LOUD. The boarding of passengers should begin with those at the back of the aircraft, not the front of the aircraft to avoid having to wade through people who are still putting their stuff in the overhead bins on the way back to the back of the plane.

Always wonderful to fly Hawaiian, they always go above and beyond to make it a wonderful experience. They had my previously requested vegetarian meals. Friendly, accommodating staff, as always.

I was pleased and I had a very good experience. The staff was friendly and attentive.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Flight delayed. They made no attempt to get our luggage to our connecting flight so I am without necessities after they begged me to check in my bag. Still dont have it.

The flight was very good. Only complaint was that the usb charging connection did not work for either me or the seat next to me so we both had to use our own portable battery to charge our phones. I also liked the fact that I could purchase Wi-Fi for an hour instead of for the entire flight.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

The flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Air conditioning in the plane wasn’t working at boarding, this resulted in a delayed departure whilst they addressed the situation. The cabin was uncomfortably hot.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

I still prefer Delta, but Delta doesn’t fly to State College PA.

There was no entertainment and the meal that was included in my flight fee was not provided.

The plane was on time and i wish they had more than cookies to give away.

I found the personal kind and caring. The Problem was not enough people to serve the the customers. The flow was restricted the crowd frustrated by the wait times. Air Canada seems to hire good people but they need backup in order to provide the service we pay for.

Take off and landing and also the crew were excellent, just we could not received one of our suitcases at Ottawa at the same time we got there, but the associate at Ottawa airport were very nice and helpful so we could receive it on 16th of September.

Service was great. Flight was delayed an hour which made our connection very tight and stressful. But we fortunately made it.

They served us 1.5 pieces of chicken nuggets with coleslaw..felt like a toddlers meal in business class. Why bother?

Flight was delayed due to mechanical issues with in-house entertainment. Strike one for the delay, strike two for no entertainment. Once we boarded we still had to wait while they tried to fix the entertainment system. Strike three was an issue with a passenger falling in the lavatory so no breakfast was served for economy seats. Not blaming the passenger but did the entire crew have to attend to one person? She walked off the plane by herself so she didn’t seem that bad off. Pretty much everything that could go wrong did but at least we got our luggage!

Seats uncomfortable There was an incident with plane Engine Pilot was reassuring. Good pilot We landed late because of this Fire engines on landing were just Protocol

Lines at gate boarding is messy. It spills into traffic which causes other travelers to snake around the boarding passengers. Need better traffic control.

Crew was rushed to get food out and left trash for a long time on our tables.
