The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

Crew was awesome, absolutely the best, Food was excellent also. Movie selection was mostly modern duds. However, I love Korean Airlines

I was handled by some very rude CSA's in DFW. I was forced to check my carry-on as I was flying economy. You are now allowed only 10 kg total on all carry-on items. As my carry-on was 10 kg, and my backpack was 2 kg, I was made to check my luggage. I find this procedure unfair, as many other passengers in economy CLEARLY had more than 10 kgs. If KA insists this is their policy, then it should be enforced uniformly for everyone. TO INCLUDE Business and First Class. They are allowed 18 kg now. From my perspective....absolutely ridiculous. This was the first time in over 35 years I have been made to check my carry-on. I am EXTREMELY disappointed 😞

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

The WiFi was not working. That made for a long flight.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

American airlines is always delayed in their flights. No access to wifi unless paid

Pilot main message was to "be nice to her crew". Crew only instructed passenger to "move out of the aisles" rather than helping passengers place their luggage. Some passengers needed to exit early to make their connections yet cleaning crews rushed onboard to make their way past rushing outgoing passengers. AA needs better protocols and better customer service for the price paid for trips.

Delayed couple hours due to airplane maintenance issues, we boarded and then asked to unboard, but cmon!! Can they do the whole maintenance prior to boarding?

Boarding was horrendous! Took absolutely forever… and the delay from the broken coffee pot was really kind of ridiculous

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

Delays and multiple changes in gates. In accurate info sent to phone. Worst flight in years. With no apologies or recompense.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

My first time flying American Airlines, my first flight to CLT was wonderful and flight attendants was nice and had great customer service. My second flight from CLT to NY was very delayed due to whatever reason the crew was not greeting other than that I’m rate 8 .

The best thing about the flight was the cabin crews in the business class. The young Asian lady was just fantastic!

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.

Boarding was so so after zone 3 was called all other zones went in

Air Canada is my new fave airline..I plan to use when I can. No complaints at all just rave compliments for the staff and airline.

I was forcefully re-routed to another destination and was delayed a total of 8hours. I have still not received my bags, no one is taking responsibility. The agents at the airport lied to me that I will get to my destination same time as my previous flight where I was forcefully re-routed from.

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

My experience with Air Canada was good. Great customer service… only a few delays and issues with the tunnel to exit the plain. I did not appreciate that we arrived at terminal D and had to go to terminal E to get the bags/ luggage.

Everything should be better, terrible flight and airport service. Delayed for 6 hours, flying around for 1 hr, and keeping us on a plane for another 2,5 -3hrs.

3-hour layover in Chicago too long. Comfortable and spacious economy seat in Chicago-Ottawa leg.
