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.

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.

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

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

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

Good food and wine. Some of the Guy who are in charge to board Passengers on the plane couldn’t use the word “Please” to direct them drop their hand luggage to be loaded on Plane bcos he said the inside storage may not have enough room for all.

Turkish Airlines apparently no longer gives you 2 checked bags allowance on international flights, so that pleasure cost me $165 for my second suitcase at the airport. On top of that, they damaged that very suitcase, which happens to be a designer one and part of a set - ripped one of the four wheels right off.

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

Very poor service. Not friendly and special food ordered but not served

It was as expected for such a short flight. No complaints

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

Packed commercial flight was as comfortable as can be expected

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.

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.
