Very good seat and service. No complaints about the food. Take off delayed due to airport traffic

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.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

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.

The best airline I have ever travel , really good customer service, attention and service !!

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

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Nothing, I wont be flying American Airlines again and will not be recommending anyone to fly American Airlines. It was the worst experience flying I've ever had.

Finnair is a really good airline! We specifically looked for them on this trip. On time, great crew, and overall great experience.

I couldn't use their app to select seats or check in because they made a business partnership with UnderPricer to control and sell those options when you purchase your tickets through that agency. And yiu can't get any assistance from UnderPricer. Vueling has made a terrible business decision to partner with them.

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

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.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

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 boarding process went very quickly, faster than I’ve ever seen boarding occur. I understand the need for efficiency, but the groups were called so quickly that there was a lot of chaos at the gate and people running through the airport. Then we all sat on the plane for a while, which seemed silly.

The flight was operated by level, who had a sister’s check in procedure (2 hours) due to understaffing and a computer malfunction. While 3 agents stood at the business check in, with a total of maybe one actual customer there at a time, a huge line formed at economy check in with only 1 agent staffing the check in. Then, my luggage was lost - a guitar case with contents inside valued at 3,000 USD. The computer system of LEVEL could not locate my bag and had no record of it, and IBERIA (with whom I purchased my ticket and the checked bag) refused to help. It was a disastrous experience and I will never book Iberia again

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

They cancelled the flight)(they said bad weather but many other flights took off) and made us wait 5 hours in line to figure out what to do. We ended up making a new flight the next day on another airlines...I hope they honor giving us our money back

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

Everything OK , except the plane left more than an hour late so I couldn’t participate in an excursion I had that morning in Brcelona

No WIFI for the flight When told the breakfast item was cheese and tomato, did not mention sun dried tomotoes - totally different flavor and not what I wanted. Flyer for items for sale but none were offered.

Awful!! Flight from Miami was delayed. Therefore we missed connecting flight. Nobody knows where our suitcases are for 2 days already !!! As far as the air craft: TVs are not working, food ala cart and even that looked awful. Did dare to taste. If you want a blanket - bring your own. Nothing is free.

I was told international flights are very nice however this one was not. We were so cramped in our seats that it was very uncomfortable. The attendants catered to the passengers that preordered their food and seemed 'put out' when we wanted to order something. We ordered a croissant sandwich and got a bagel sandwich. My husband ordered a coffee and never got it. We were so thirsty and had to go looking for someone to get some water. The food was horrible. The bathroom was filthy. The movie selection was not good.

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

As I said Al & AJ were absolutely the best and wow they should be recognized for their amazing service!

Flight was on time. Boarding process was tedious. Not much overhead cabin space. Seats very close (front to back). Uneventful trip just the same.

The crew will not help you with the overhead bin even if you are business class. If they do, there's always the sentence " we are not supposed to lift anything".... To charge for seat assignment in business class is nothing short of money grabbing/ ripoff. The ground service in London is better than Vancouver, which was atrocious.

Quick boarding process, slight delays on the tarmac prior to takeoff and a late arrival due to an emergency on the landing runway. Not the fault of the airline at all! Cabin crew was very friendly and the Captain kept the passengers well informed about what was going on

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Excessive delay without proper communication. Mediocre for a BA flight.

Another old plane. This time they changed gates at the last minute and when people arrived boarding was delayed

Still unhappy cancel fight rebooking half of what I paid fore! Terrible!!!!

The food was awful and little, on the plane there was not space to even move in the aisles, the seats were super close to each other, no confortable at all!
