I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

Glad you had Bibimbap which tasted much better than mesh potato or pasta.

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

So far one of the good one , whenever I go to Korea , I always use Korean airline .

They could have had more up to date movies/better choice of music.

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

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.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Logan airport construction meant that boarding was chaotic crowded and delayed

Everything was great. Great service, excellent communication, and early arrival

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Free Wi-Fi is good. That’s all - food mediocre, unfriendly crew, poor communication after trying to file a claim for my lost bag, which Delta didn’t even know was lost until I told them.

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

Check in was not available online. It was super long line to check in

I did not have a good experience from the first point of contact to the check in person to boarding and the comfort of the seats. I would not travel on Turkish again. I will let my family and friends know about my experience which was not a pleasant one.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

Cross Atlantic flight terrible aircraft TK10 on the way back : Old configuration tacky . The boarding in Istanbul at the gate fly TK686 was a mess unorganized , very rude ground staff . Overall never again

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

I enjoy flying with Turkish Airlines and such good hospitality among the crew memebers

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

Flight areas delayed 3 hours , train in the airport didn’t work

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

Check bag location is full of rude employees who are unwilling to assist with issues after talking to AA on the phone and relaying messages. The boarding was good. While on the flight it got really hot. Asked flight attendant if there’s a way to drop the temp and make it more comfortable as we are flying from DC to Miami so flying from cold to hot weather. No changes made. Stayed hot and uncomfortable on the plane. When asked again about the AC being down the flight attendant said no the WiFi was down but not the AC. I mentioned it was still hot. No changes.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

Great - quick boarding and landed early with an available gate.

Very good. Very efficient. Entertainment was not functioning both ways which was disappointing.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

My first flight left so late we knew I would miss my connection. Rather than redirecting me then, they made me take a flight to Montreal, then Toronto (there was a flight leaving for Toronto when I was in NYC, no need for me to also go to montreal). Then they gave me a food voucher that did not work (4 places would not accept it). At least they gave me a hotel automatically, even though it was a cheap crappy one. I'm still not home, and it's been over 24 hours. I'm exhausted.

Liked the size of seats. Not much food offered given length of flight.

The boarding was at a dual gate hallway and there was only one spoken explanation about which way to turn to board the correct plane. It wasn't marked visually at the split in the gate. The phone charger did not work at my seat. The temperature was quite chilly throughout the flight and the recorded announcements were extremely loud for a small plane.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Flight was delayed 1.5 hours as crew was stuck in traffic...that is absurd that the airline would be transfering a crew by car through NYC during rush hour. I missed my shuttle bus and got stuck in Vancouver for the night. Airline did not offer a voucher

I booked these flights for our group of 4 people several months in advance. On the departing flight, I checked in 24 hours before flight and was able to select the seats that we liked. On the return flight, I had no internet access until about 12 hours before flight, when I tried to check in, we were scattered all over the plane in middle seats which is absolutely ridiculous. I book all 4 ticket in 1 booking MONTHS in advance, the preassigned seats should be together, NOT scattered in 4 different rows in middle seats.

Very unfriendly crew, Air Canada should hire staff that are willing to do their job and be friendly to others. Unmannered flight attendants.

It was absolutely awful in every week. A mechanical failure led to a 6 hour delay, cancellation and rerouting.
