The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

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!

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

I had an extensive delay on my previous flight and we had another delay due to the crew not being there. We were scheduled to have a late arrival but due to the delay it was even longer.

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.

All very good The food definitely lacks quality and at breakfast I was given a small muffin small orange juice and not even a coffee or tea were offered It would have been nice to have that first thing Apart from the food everything else was excellent

Boarding was extremely efficient; I appreciated the back-to-front loading strategy. The instructions from staff were very clear and thoughtful, and they were friendly and generous with service. In-flight entertainment was top-notch.

The check in crew were so friendly and attentive. Probably the best in my experience and I’ve been flying at least four times a year most of my adult life. Very considerate and I appreciate it.

Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.

I was disappointed with my experience on my Aer Lingus flight from Denver to Dublin. One of the biggest issues for me was the attitude of the cabin crew. They came across as cold, unfriendly, and unapproachable. There was very little warmth or friendliness, and I rarely saw anyone smile. I did not feel that the crew made passengers feel welcomed or cared for, which makes a significant difference on a long international flight. The cabin was also extremely cold and uncomfortable. What made this more frustrating was that we were instructed to put everything, including our blankets, underneath the seats at certain times rather than being allowed to keep ourselves covered. Considering how cold the cabin was, this was particularly uncomfortable. I also did not appreciate the tone used when giving some of these instructions. At times, the communication came across as unnecessarily loud and abrupt rather than polite and courteous. I understand that cabin crew have important safety responsibilities and passengers need to follow instructions, but those instructions can still be delivered in a professional, respectful, and friendly manner. Unfortunately, the lack of warmth and hospitality from the crew was the most disappointing part of my Aer Lingus experience.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

Awful customer service. What you are told 100% depends on who you talk to.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

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.

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

On Time. AA is late due to maintenance all the time.

Flight attendant super rude demanding I remove my carry on baggage from overhead and place under seat. I stated I am an ADA passenger and need the leg room as the seats are very tight. That’s why I boarded early for the extra time to get situated. She said, we need the space. I replied “How can that be as only a few passengers have boarded so far? I am executive platinum status so I understand the rules and you are discriminating against ADA federal law. Please stop”. Her answer… then you should find another flight! Not ok. Addressed with senior flight attendant. So unprofessional and discriminatory.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

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 .
