6.0 GoodAnonymous, Oct 2026
The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable
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
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 😞
I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!
Great as one can be for a one connection 6 hour flight
On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.
Everything was great except the fact that catering did not restock the flight from ATL to GRB and we were only offered water.
The WiFi on the plane was out. I also thought movie options were lacking.
These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.
My seat was changed without my consent. It wasn’t a major deal but annoying.
It was delayed over an hour and a lot of announcements disrupting movie.
Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!
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.
Just having a little bit more legroom would've been nice.
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.
There should be a visible sign of Air Canada, because I walked all around and I didn't notice where was the desk, I was in a rush for the time because it was very difficult for me to find the D gate.
It was impossible for me to make the check in for Air Canada. Then it was very difficult to find the D gate in Houston airport . I hadn't have enough time to make it. Finding the gates in Houston it's so confusing. This was about my connection.
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.
3-hour layover in Chicago too long. Comfortable and spacious economy seat in Chicago-Ottawa leg.
There was a 4 hour delay, some of which was attributed to ATC weather but started with maintenance and then later also log books. Though the flight went far beyond the scheduled time, there were no accommodations such as additional meal options or anything else.
Delay for 1 hour due to maintenance issue and late boarding
Had issues (application error) selecting my seat before checking in. Return Flight was delayed over 2 hours. Sat on the tarmac for 20 mins after landing Overall, not good of an experience compared to the times I have flown AA. Not sure I’m coming back.
Got to gate late and they made me check my bag but when I got on flight there was lots of overheard bin space .
The intuit carrier I have flown with that doesnt have WiFi available on board - at least not on the A380. Meal I wanted wasn't available and the meals I did get were all served cold to warm at best.
The flight was delayed and gate changed so that was not fun and the flight to Dallas from LAX was very delayed on Sunday. It was just not a great experience due to the delays both ways.
For super long flights Premium Economy is the way to go. But the lack of WIFI onboard (don't you think it should be free on a 14 hour flight?) and the sparse personal entertainment selection made this the biggest detractors. Also, can we keep that map from flashing in our faces the whole trip there? Jesus Christ.
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 .
