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

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

My experience with Delta is always pleasant. My return flight #1426 from ATL to RIC was very delayed with departure and landing. It also took a substantial amount of time for baggage claim. It was already late at night, so the delays made for a very long day. I did not get home until after 12 midnight.

I had a great flight with delta. Plane was clean and the staff was nice, I would fly again with delta.

After flying with Qatar Airways and Kenya Airlines. Delta leaves a lot to be desired

A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?

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 overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

Packed flight and not sure why dinner service would start at midnight while passengers we’re trying to sleep

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

All our luggage arrive wet a lot of damage on it and in bad situation, broken and open

everythings was good only the food is bad they don’t have enough food for all peoples they have only pasta and when i asked them about beef they said we don’t have

First Flight got delayed had to get rebook for another plane ride to connect the next day the process was not helpful at all had to figure the whole processs myself poor service plane was small and customer service was horrible will not fly this airline again

Excellent overall. Boarding was a mess. Queue up too early, takes too long for them to start boarding but they want everyone to queue up and wait and wait.

When getting to our seats a blanket, headphones and pillow where there already. The food was very good and plentiful. I liked when they came around w/hot towels to freshen up with. Slippers, socks and an eye mask was a nice surprise. My husband and I have mobility issues and the transporters were absolutely wonderful and helpful w/the wheelchairs at each stop. Getting from one gate to the next they were a blessing.

The taxi drivers are very rude. Didn’t wait. They said you come in 5minutes or I leave. Did not leave any messages on front desk and they left. We have to hire new cabs in turkey.

Everything was good except for the seating arrangements. We could not get seats to be seated together with my wife. We’re unfortunately.

My first time in business class The in flt staff was outstanding in every aspect of service, the food was amazing, the business seat space made the 11 hour journey easy peazy

It was good, but always can be better. The airplane was old.

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Starlink internet made the flight time shrink and I was able to work.

Tiny seat made for midgets. You can’t put a normal size human in such a tiny seat for 8 god damn hours! Hot plane, no air. Lost bags at Rome airport for 8 hours, lucky to have found them. Horrible flying experience, United Airlines should be embarrassed!

The issue is the flight is delayed, which causes me Missing the connecting flight by 3 mins. Remember the connecting flight is a US codeshare flight so UA should be able to inform the operating airline about the delay.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

I have generally had positive experiences with American Airlines (outside a handful of delayed flights), which is why I wanted to share this feedback constructively. On my recent flight, my travel experience was extremely uncomfortable because my seat mate significantly encroached into my assigned seat space for the duration of the flight. As a result, I was forced to sit partially sideways, with much of my shoulder and upper body extending into the aisle. Unfortunately, my back still hurts from maintaining that awkward position.I recognize that this is a sensitive and challenging issue for airlines and cabin crews to address. Everyone deserves to travel with dignity and respect, and I understand that individual circumstances can vary. However, fairness also requires that all passengers have reasonable access to the seat space they have paid for. When one passenger's use of space substantially impacts another passenger's ability to sit safely and comfortably, there should be a practical solution available.I appreciate the complexities involved, but I hope American Airlines will continue exploring ways to ensure that all passengers can travel comfortably and equitably. This experience detracted significantly from what should have been a routine flight.

The crew was great! The issue for me is the aircraft. The Airbus A32x is just not comfortable enough and the entertainment delivery via personal devices is problematic.

The crew was dis respectful even in business class. I will not recommend AA to anyone and will also fly only when there is no choice

Three aircraft in succession experienced maintenance issues, resulting in a six-hour delay. The original aircraft required replacement, and the substitute aircraft arrived more than two hours late. Passengers boarded that aircraft, only to be told later to deplane due to maintenance concerns. We then boarded a different aircraft that had arrived at the gate, only to be instructed to deplane once again because it, too, experienced maintenance issues. After hours of delays and two separate boarding and deplaning events, passengers were directed to a third aircraft departing from a different terminal and had to rush across the airport to make that flight. That was the only aircraft that ultimately departed without incident. Of course, passenger safety must come first, and I am grateful these issues were identified before takeoff. However, when three aircraft in succession require maintenance attention and passengers are repeatedly boarded before those issues are discovered, it raises legitimate concerns about American Airlines' preventive maintenance procedures and aircraft readiness checks. One aircraft with an unexpected issue can happen. Three aircraft in a row, combined with multiple boarding and deplaning events, suggests a pattern that warrants review. American Airlines needs to take a hard look at both its maintenance practices and its decision-making process for boarding passengers before determining that an aircraft is ready for service.

Overall, it was a good experience, although the boarding process was somewhat disorganized, with no clear signage or designated areas indicating where passengers in different boarding groups should line up. Additionally, the seats felt quite outdated and could benefit from modernization. While the cabin crew provided good service, the experience lacked the personalized attention I would have expected.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
