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

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

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.

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.

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.

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.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

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

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

They overbooked the flight by 3 people. It is completely unacceptable to tell 3 people, with paid tickets, that need to get home for children etc, that they need to stay another night. No compensation. No apology.

It was a short flight but everything was great! I would fly with British Airways again.

Delayed flight due to lack of crew caused me to miss my connection

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.

It was difficult to board from London to accra. Had to get there an hour before and almost missed the flight. Did not get enough rest time at the lounge

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

We found the bag drop/ check-in proceedure at T5 unnecessarily complicated. We paid extra for seat selection in advance and were allocated worse seats at T5. We found the check-in person was not particularly helpful although the the staff at the gate were super good.

Very dated plane. Seat was firm and uncomfortable. Entertainment system almost laughably outdated. Poor audio. Picture was always too dark.

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.
