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

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

The WiFi on the plane was out. I also thought movie options were lacking.

They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.

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.

The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.

The staff and crew were wonderful. The delays were atrocious. The missed connections problematic. Getting home at 4am and having to go to work at 8 am, not a great situation. The gate agent in Huntsville was amazing. She helped everyone efficiently and with excellent problem solving skills. Her communication was helpful, timely, and thoughtful.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Great quik boarding, friendly gate agent and crew. Let early

I somehow thought my food preferences was saved to my account— everything had dairy and couldn’t eat anything.

Breakfast before landing was a reheated breakfast “calzone” which was not good, at all. Otherwise, food was good. Crew not very attentive for taking trash from passengers being a little slow in eating.

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

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.

There were not enough extra leg room options to purchase. Also the seat Infront of mine was broken and the gentleman literally laid back into my lap for the whole trip. This was the most uncomfortable trip I have ever been on

A lot of things can be done to improve in flight experience

Average at every level . Poor entertainment selection. Boarding was very poor and disorganized. Flight was late by one hour .

Spent over $20k on for business class tickets from DFW. They used a very old Boeing 777 with old Business class cabin which was unclean and stained seats. On a route they normally operate the modern Boeing 787. The cabin heat was set to hot for 11 hours. On the IST LHE route the business class experience got even worse. They operate an even older Airbus A330 where trip was falling apart, seat recline did not operate and the whole experience left us hugely disappointed. Next time we likely will shift to better quality product which stands up to their hype. Turkish need to relook at their fleet plans and not use their worst assets of perceived week markets such as Pakistan.

The flight from Houston to Chicago was delayed, causing us to miss our connecting flight to Madrid, losing our Rental Car booking in Bologna taking alternative travel routes to get to our initial destination in Pizza by the 15th. We got the notification of the delay as we were traveling the 3 1/2 hours from Corpus Christi, Texas to Houston Texas for the initial flight. The delays hauling luggage all over Milan‘s Central train station to catch trains to get to Pizza the same day resulting us arriving in Pizza at 2 AM leaving us no time to rest as there was a 9 o’clock checkout time the next morning. The first 72 hours of the trip with nothing but headache, a knee injury from the excessive walking and a delayed car rental replacement, which ended up costing significantly more.

The united employees at the gate treated me very rudely and called me nefarious

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

The crew was good, the WiFi was amazing, but the plane was meh. Uncomfortable first class, not enough room for baggage. My stuff ended up being behind my seat, so I had to sit on the plane for 20 minutes before I could get to it after landing.

food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

From the boarding crew to the FAs was such a good team. All with smiles and positive energy. The pilots made an announcement of us waiting on some passengers who were late landing and I didn’t hear one person feel like it was an inconvenience which was wonderful. Massive kudos to all that worked that flight. Everyone was united. 😊💙

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.

Flight took additional prep time since plane came from Mexico, which resultrd in boarding and plane prep being delayed for additional cleaning procedures. Once boarded, plane tire was identified as being low on air and needed to be replaced, which creared the need to deboard and further delays for what was already a late night flight. Would have expected a better scheduled turn around and prep buffer that would have not created that degree of delay and deboarding

Very cold on board it was like having 16hours sitting in a fridge

My luggage was lost at some point during my layover between Chicago and LHR. I landed Tuesday morning, and did not get it until Thursday night. Ironically, the people at the ticket desk had added a “priority” sticker to my tracking tag.

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

The customer representative that helped me when I checked in was horrible as she told me I couldn’t check my bag because I missed the 45minute rule by 2 minutes - because of the line at the counter My connection flight was delayed too

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.
