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.

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

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

Delay getting into gate in ATL caused delay in bags when getting to BWI, disrupting evening plans with family.

6 hour delay including one after we were boarded. Horrible experience.

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

Food choices were very limited. Taste of the dishes was average.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The lady who gave me my boarding pass for check in was extremely rude.

Small plane (and thus a bumpy ride), small seats (and a large man next to me), absolutely terrible wifi, and no food options to speak of.

Plane was older and terribly uncomfortable but the leg room was good!

Kayak, the site I went through to book our flight, sent very unclear emails about flight changes. Kayak was incredibly unhelpful in their communications with me about this, promising to work on resolving the issue, and failing to do so. As a result, I needed to get a hotel in Brussels and am now in the process of trying to get reimbursed. On the other hand, the flight personnel in Brussels were very helpful, taking time to look into the issue and determine if they could help. I am very grateful for them and have no problems with the airline. For Kayak, however, I will never use it again and will never recommend it to anyone, and will even discourage people who consider going through that site. My worst experience ever....

It started well but flight was cancelled and they created a nightmare rebooking. It is two days later and we still haven’t reached our destination. I am in Amsterdam waiting on transfer desk to open (later than other airlines) to hopefully get a boarding pass. Once that problem is solved we will just pray this flight isn’t cancelled too.

They messed up my seat so I didn’t get the one I paid for

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

The Lufthansa flight was delayed, and I missed the connecting flight. Lufthansa customer service have not been helpful in rebooking the subsequent flight with Air India (another airline that is part of the Star Alliance). Lufthansa told me it's not their responsibility, and Air India says the PNR is part of Lufthansa, so they are not responsible for rebooking. Lufthansa customer service asked me to contact the counter at Delhi airport, but no one was available there. I am caught between these two airlines, and ultimately, Air India decided to reschedule my flight after 18 hours. I am stranded at Delhi airport. I can't go out because if I do, I can't come back in, and I can't get past security to get food. My 3-year-old and our family stranded here for 12 hours without food and water.

Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.

Bordón could be bettet if the company say before boarding the order of the different groups.

Boarding was so bad in Frankfurt to mumbai total chaos no directions no boarding order

Flight got cancelled and we did not get an email till the last minute. They rebooked us on British Airways for 6 hours later and did not inform us. We drove all the way to the airport for the AA desk attended to take a while to figure out our flights were cancelled and rebooked. British airway attendants did not show up till 4 hours later! Really poor customer service

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons

bad, made it to connecting flight and they didnt let me board

Our flight was cancelled on Sunday morning. We were supposed to take a short flight to Dallas from Austin, then a nonstop to Barcelona. We were rerouted from Austin to Miami on American Airlines due to storms we sat at the gate for 2 1/2 hours, pilot announced we needed fuel. In air pilot said we were rerouted to Fort Myers 30 minutes from Zmiami. Sat on tarmac waiting for a gate. Deplaned at 10:09. Pilot gave conflicting info about what to do. Missed Miami flight to Barcelona. Pilot announced crew was timed out and we would have to wait for a new crew. Waited a couple of hours. Got to Miami at 2:30 am. Gate agents at Fort Myers told us to go to D30 for hotel vouchers. No one was there. So we slept a little on the floor. Husband is 80 and I am 74. Rerouted to JFK at 9:54 am on Monday, then flight to Barcelona at 5 pm. We arrived in Barcelona a day late and missed the first night of our Oceania Marina cruise. We feel that we are due a lot of compensation for this trip from hell.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

Surly rude flight attendants. I ordered the chicken and was given a vegetarian meal with no explanation and no opportunity to change it. I tried to order another beverage and was told by the young humorless flight attendant to “wait”. And she never came back. The seats were very uncomfortable and cramped. The last time I flew British Airways was many years ago but I remember it was amazing and the crew were very charming. This was a terrible disappointment given the cost of the flight.

I have something to say about the flight I took from London to Gothenburg, after my flight from Austin to London. I fly a lot and have done so for decades. I first flew to Scandinavia in 1973. My former wife is Norwegian. The main thing was the experience at the Gothenburg airport. Three flights from Britain arrived around the same time. So there were huge lines at immigration since Brits are no longer a part of the EU. After over an hour in line, I finally gave my passport to the immigrations man. You’d have thought I was an Afghan. I just barely got into Sweden. I had to answer all kinds of blunt questions. I had to show all kinds of onward tickets, addresses of places I’d be staying and it was pretty daunting. Perhaps it has to do with the situation with Russia. British Air might have done something to prepare people that things have changed a lot and they’d better be ready to run the gauntlet when trying to get into the country here. Thanks for listening and taking this into consideration. Sincerely, a senior citizen of the USA

Our original flight booked in First Class was delayed to the point we would make our connection at DFW so AA rebooked us on an earlier flight in Coach. No mention of giving us credit for the difference in cabin class.
