You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Overall excellent service and Frankfurt Airport was very efficient and clean

I came out early, 4 hrs before departure. The flight was changed 4 or 5 times with few minutes between new and schedule time , then 30 minutes delay, then up to 2hrs 30min delay. When I arrived in Frankfurt, no one help us to lead to the custom service. After almost 1 hour asking around then we must line up for another hour to get overnight and rebooking the next flight. We must find out how to get to the hotel by us self. The shuttle bus driver in Germany was not nice, speak German to English speaking and we must predict what she / he tried to tell us. We got up earlier and tried to not coming late to the check in and immigration procedure (we were told by the helping center that the immigration used to be over crowded) then we came there it was almost empty, then we must stay in the airport for hours not necessary. We got the coupons at the airport for compensation for waiting for delay flight for NOK 75 ( as low as 6 Euros) It is not enough to buy food at the airport price and Norwegian cost of living... How to drink a cup of cappuccino for NOK 72 when the stomach was empty for food in 16 hrs (from dinner at 6 pm the day before to 16 pm the day after) At the hotel in Frankfurt, we were offered two options spaghetti with biff or vegan food and a drink for 18 Euro. Almost 60 passenger ate the same food and I was remembered once time in former Soviet Union in 80's I travelled with Aeroflot and the passenger were stranded in the hotel for next flight and we were also offered only one choice of dinner, if we were hunger we must pay 1$ for 1 egg and another 1$ for two loaf of bread and butter. I can't believe Germany is to poor and inferior service like former USSR in 1980 decade. My good remembering of Luft Hansa disappear and changed totally by this service I got this time.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Because of the fog at the Frankfurt airport, our flight was delayed leaving Budapest. We only had 20 minutes to get from A23 to C13. This was quite a walk for this not-so-young anymore lady--even with the help of moving sidewalks! We also had to go through passport control and then security. Germany is extra thorough, even doing pat-downs of all passengers. We got to our gate and I knew I had been randomly selected for extra security scanning because of the "SSSS" code on my boarding pass so I wasn't surprised when he escorted me back to security to be searched some more. The boarding gate gentleman assured me that they would hold the plane. The ladies in security rushed through the scanning process as fast as they could and we were able to make our flight to Orlando. The actual flight was smooth and comfortable. The food and service were excellent. The flight crew were friendly and efficient.

SAL to FRA - Original flight was cancelled less than 10 hours before scheduled. Did receive lodging at no cost for 1 night. Coordination between Lufstansa and hotel was very poor and we had to pay for a meal we thought was to be paid for. Traveling from SAT to Denver coordination between Lufstansa and United was very poor and we paid double for our check-in baggage. We are hoping to that refunded. We wish other airlines would fly to Salzburg as we plan to visit more often.

They gave us free up grade to a roomier seat.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I paid for extra legroom which was not honored and have spent hours trying to get a refund for without success. I have since come to learn Lufthansa has a habit of reassigning seats and making it impossible to get refunds.

I was expecting better from Lufthansa. I’ll think twice before I book Lufthansa again. This trip was the worst ever… in my 70 years of traveling.
