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!
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.
13 hour delay stuck in Detroit and missed a day of meetings. It was terrible
Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.
The cabin was definitely dated, but that's about par for the course. The flight crew were wonderful as always (always a Delta highlight), but the boarding process was slow with little direction or encouragement to get people in their seats quickly since we were already delayed.
Totally organized, quick boarding, professional staff and ON TIME! Good size seats in the cabin Wonderful experience
The flight was delayed to board, then delay in landing and extremely bumpy landing.
Could have been on time and not missed my connection
Flight Staff: Always great! Checking back vs carry-on: I typically check my bag since so much time is spent stowing the bag, it's heavy, maybe not enough room. Delta is charging $45 to check bags. Yet, the people who have multiple carry-on bags are then asked to check their bags and are offered this service for free. This does not seem fair to a person who is trying to be proactive in improving the process . Boarding: Boarding is always slow and exhausting. With the exception of First Class, Economy, why not board the zone in the back of the plane first??? Seats: Why cross the seat belts? I get that it looks nice, but people waste so much time moving them or sitting on them and then having to move. Seats: On both my flights the seat did not recline. Not a big deal. Smell: There was a horrific smell like the restrooms on my first flight. I thought I was going to be sick. Most flights do not smell great. Does Delta use air purifiers or anything?
Terrible - the flight was delayed taking off after boarding. Then the flight circled lga before landing. Significant delay
The flight was delayed at the very last minute and no information, both of my round trip flights were delayed at least the BNA to Boston was informed earlier but the return one was horrible
Delayed, then set on termac before taking off for 45 minutes. After landing had to sit on termac for another 30-40 minutes. Total disaster of a flight
Our flight delayed, due to the incoming flight arriving late from Paris. AF caused us to miss our connecting flight, also booked through Air France directly. They couldn't accommodate us until later that night, and we had to be in AMS earlier than that. They won't do anything else to help us and wanted to charge us more money to rebook us too. Not great service, since it was all their fault.
Seats! The eternal problem in economy. They are like stones!!
Everything is good except the seats are tightened no rooms for the legs,
The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)
It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.
It was an OK flight with below mediocre service by their flight attendants
Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.
The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.
I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.
Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .
We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.
Well, I think we left close to on time. Crew was “eh”.
Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.
The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.
Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?
Food was very bad. Boarding was disorganized and messy. Crew was friendly
Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.
Great travel. Wonderful experience. Hope to do it again in the near future. God willing
The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.
All OK. Food, best bring your own. Even a BigMac will be better.
There was more leg room in what was most likely a basic assigned seat (row 25) then on other airlines I've flown lately.
My overall experience with JetBlue was pretty poor and disappointing. We originally booked a DIRECT flight home from Boston on 9/28 at 8:00pm even though it cost more than the non direct flights. With no reason other than "unforeseen circumstances", our flight home Monday was cancelled and we were rebooked on a 7:00am flight on 9/29 with a layover in JFK. We were traveling with sick kids coming home from a funeral of a loved one and needed to be at work on Tuesday so paying extra for a flight home Monday was something we had to do. The original direct flights were considerably more expensive than the non direct flights- so I don't understand how Jetblue did absolutely NOTHING to compensate or right their mistake. We will not be booking with them in the future because they are not reliable and they showed no remorse nor did they make any attempt to make things right. The least they could have done was credit the difference in cost of flight because I know our original flights cost more than the one we were rebooked on. Once again- we will not be flying with them in the future and will advise family and friends to be aware of the risk you run when giving them your business. Do better.
Terrible. We originally booked a direct flight from BOS to MCO on 9/28 at 8:00pm and it was cancelled due to unforeseen circumstances and the flight we were rebooked on was on 9/29 at 7:00am with a layover in JFK. We were traveling with sick kids so leaving at such an early hour was absolutely miserable, and on top of that we all missed work which we couldn’t afford. On top of that- we paid a fortune for our flights to be direct without a layover and the flights with layovers were cheaper so at the very minimum we should have been refunded the difference. With absolutely no explanation or sympathy from JetBlue- we will avoid using them in the future due to the fact they aren’t reliable nor do they correct their mistakes.
Experience with JetBlue was poor. We were originally suppose to fly home on a direct flight on Monday the 28th at 8:00pm and we it was canceled due to “unforeseen circumstances” and we were rebooked on a 7am flight on Tuesday the 29th with a layover in JFK. Traveling with sick kids and waking up at an ungodly hour was miserable, and not only that it caused all of us to miss work. We intentionally flew our Monday on a direct flight and the direct flight was far more than the non direct flights on any given day. There was no compensation provided let alone a reasonable explanation. When you are charging people those type of prices for domestic same coast flights- you should be at least refunding the cost difference of the flights if you are rebooking them on a cheaper flight. I will never fly JetBlue again because they are unreliable and don’t correct their mistakes.
Wasn’t very happy with our flight home due to the fact it was cancelled with absolutely no reason. It was a direct flight at 8:00pm on Monday and they rebooked us for a 7am flight on Tuesday with a layover. Traveling with sick kids, getting up that early was miserable and on top of that we all missed a day of work that we couldn’t afford to with absolutely no apology or compensation from JetBlue. The original cost of the flights were astronomical because we flew out on Monday over Tuesday and also we paid extra for the direct flight then we would have for the flight with a layover. Super disappointed Jetblue truly could have cared less. Will avoid them in the future due to the fact they aren’t reliable nor compassionate for the inconvenience these changes cost their clients.
No WiFi, no power to charge phone, confusing boarding, delays
There is a considerable amount of people that use the wheel chair pre boarding along of large groups of family / friends. This is not right should be limited only to the person in need and the airline assistant. Some of these people use overhead bins that do not belong to them. The aircraft had a non functional wifi . The service was bad.
Overall, it was a fantastic experience had no movies up charge for everything haven’t flown in many many years. Crew is fantastic. Flight was good overall great experience.
My sons tv wasn’t working and they didn’t give him a kids meal I have to request it prior and no one told me!!! Then the 2nd flight they split us up. My two year old can’t sit alone on the plane hello?????
Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.
