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

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Although I know the Airlines cannot control the situation when there’s a ground stoppage, it would’ve been nicer if we would have had more up-to-date information clarity around the delays. Additionally, I think the delays also took a toll on the Cabin crew, particularly the lead flight attendant in first class. She was not very friendly when we boarded the plane for many of the passengers. Number one she refused to hang a garment bag in the front closet for a first class passenger, she was unwilling to dispose of an empty bottle in the trash as I was boarding (despite drinking a bottle of water herself and needing to disregard), and she was very combative with a passenger, who needed to access something from his bag that was Gate checked. Frankly, it was really unfortunate as I’ve never seen a flight attendant behave that way directly to the passengers, particularly when none of us had done anything wrong.

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

While it wasn't the crew's fault, it was a frustrating flight. We sat on the runway for 2+ hours. Both of the flight attendants were excellent and did a great job checking on the passengers. The pilot did keep us informed about the wait. I appreciate the crew apologizing for LaGuardia airport's backup.

the flight got cancelled - few hours before the departure time - no time to change

This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.

The meal tray was not usable it was completely uneven

My experience with Delta started with my luggage being found ripped open with items missing. The baggage office told me to bring the bag, and I wanted them to see how I found it. The agent refused, so I carried my bag into the office myself. The agent was nice enough to fix the zipper and gave me a red card with a number to call. I followed the steps; first one department, then the baggage department took over. This took more than two hours on the phone. The return flight was okay. The flight lead was checking her meals and then asked if we wanted anything before departure. However, throughout the flight, I had to ask for things because she was reading her book;which I have no issue with if she had been more attentive. At the end of the flight, the pilot appeared annoyed with the flight lead for not following his instructions regarding a meal he had requested; a chicken sandwichand said, "I asked for that for the flight." On the positive side, my work event in Vegas went well, and now I'm home relaxing.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

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

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.

We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

To get to jet blue at JFK from any connecting flight you have to go through security again.

Amazing! One of the best kept secrets in air travel!

We fly Bussines class and we didn’t feel like it is. Out luggage didn’t arrive and we have to return again next day from our hotel to airport to get them. Still waiting. No information from Turkish airlines Very poor customer service I think booking through kayak it was wrong decision

Three screaming and crying children in business class made it very difficult to rest. The crew made no attempt to address the situation. I might as well have saved the money and flown economy. The parents were oblivious to the discomfort their children were causing. The lounge in Istanbul is wonderful, but did not make up for the misery on the flight. My business class seat power outlet was broken and I have a cpap. The crew couldn't fix it or move me to better seat. Fortunately , the passenger in front of me allowed me to plug into his power outlet.

Could have been better. Bag rechecking could have been eliminated. Gate location and direction need to be clearly stated.

I flew Business with my daughter and son. The service, friendliness of the staff and the comfort of the fully flat beds were phenomenal. Would definitely fly Turkish again soon.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Staff and flight attendants were very polite. Flight was smooth. My seat on the plane was a bit broken so it would not stay in upright position but it was fine for the most part.

Flight staff and all was fine. Food always sucks on planes so nothing new.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

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.

It was very hot on the plane and it wasn’t acknowledged by the crew. This whole trip was one of the worst flying experiences I’ve had in a while. We sat in that hot plane on the tarmac in SLC for 45 min (after being delayed for 33 min for crew). 4 hours in the air in a barely cooled cabin. Over 30 min sitting on the tarmac in CLT waiting for a gate. I missed my original connection but was fortunate to get on the last flight out to RDU so I can make my 2 hour drive home. I know these things happen. But it’s frustrating nonetheless.

gate crew was courteous and helpful, flight attendant was nice and friendly once we got going. But we pushed off from the gate relatively on time, then sat there like 10 ft away, for an hour, with no announcement or explanation. Taxiing then took forever, and I get that there was runway congestion, but would be helpful to keep us posted on whats going on

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

My flight was delayed several hours, which is to be expected (American never fails to disappoint me!), but the parts that really bothered me are as follows: 1) I was unable to add myself to the standby list for another flight in the app, nor could the gate agents figure out how to help me do so (the app is difficult to work with and simply did not allow me to perform the action of adding myself to the list) 2) When I asked the gate agents to add me to the standby list, the agent said that he had added me, but I was not able to confirm that I was on the list in the app; as it turns out, I had NOT been added to the list after all. He had lied to me and/or failed to add me to the list. 3) I figured out I had not been added to the standby list when I spoke to the (rather rude, snippy, and dismissive) other gate agent, who finally did add me to the list after giving me some pretty unnecessary attitude. I understand that gate agents experience the worst of stressed travelers every day, so I appreciate that I was eventually able to make it onto the standby flight with their help. However, the app needs some SERIOUS attention!

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.
