There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

Good experience, just i couldn’t connect me to the wifi

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

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

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

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

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

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.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

Good value for the money. Good leg room. Take off and landing very good.

Seats are very small, I’m not a big person, but the person beside me was using his seat and half of mine… and this person was a bit gross but not a lot…

expedite passengers through passport control when the airport authorities are processing inefficiently.

the boarding took a really lo g time, we were standing on stairs waiting to walk out to the plane. Seats are uncomfortable but it’s ok for a short trip. There is no entertainment. Follow the rules and will not have any problems or extra charges

Be on time and staff on airport could be a bit more nicest

You have improved through the many years I have flown with you. But you still nickle and dime your customers. I paid extra for carry on and priority boarding.

Great flight and crew but let down yet again by the disaster that is Birmingham Airport

Crowded, little leg room, little lateral room. Hour late, then all funnelled into a small room with a couple of bench seats for 150 people. Most sitting on the floor or standing for 30 mins before chaotic boarding.

You can only check in maximum 2 hours before your flight. But it’s not written anywhere on your ticket or your boarding pass or in any of your emails. The only sign is at the beginning of a huge snake queue on the barrier which is easily blocked by people. So you queue for half an hour only to be turned back. Plus on the flight we paid for priority which included two carry on bags in addition to our backpacks plus I had a letter from Ryanair for my CPAP machine to be allowed as free carry on as well. As it happened, we only had one carry on and the CPAP and two backpacks and the agent insisted I shove my CPAP under my seat which I refused as it wouldn’t fit without jamming it. They had oversold priority (or didn’t check bags) and there was an enormous fuss about overhead storage. Poorly managed and the inflight ordering service didn’t work. It was awful. I will never fly them again. And before you say it was cheap, it was most certainly not. So Ryanair can kiss my business goodbye.

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug in was broken, especially we are with 5 years old who like to watch a movie

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

App totally screwed me up trying to check in. Would not let me select a reasonable seat and therefore I was stuck in a totally uncomfortable seat for 7 hours. Will not take the chance again and use other airlines in future where no issue choosing seats

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

Not being stuck in the middle seat between strangers but that’s not the airlines fault

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

I was at the airport 10 hour early. I would have loved to drop luggage in advance but this was possible only 3h before the scheduled time, however BA was so kind to move me to the earlier flight as it had space available at no extra cost. Thank you!

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

It was great. We arrived a few minutes late but the crew were concert and kind about it. It was a nice smooth fly thanks be to Jesus. I prayed for smooth flight and Yahuwah answered my prayer.

Need more check in desks at Marrakech. Even if you are travelling with hand luggage only, you still need to 'check in' to get the old style boarding pass. Unfortunately they haven't thought to separate out the people checking in luggage to a separate desk. Flight was delayed leaving but arrived on time. Limited food options on board and very overpriced.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.

After you made us check-in I tried to add a suitcase in the internet and also to get help by chet. Nothing work and we pay 60 pounds at Airport. Comper to Easyjet to do the same, was easy and customer friendly.

Boarding was like being hoarded like cattle, all penned in in an area way to small

I missed the flight from Manchester to Dublin because of poor informations from Aer Lingus and the airport, no possibility to check in online, they don't respond to phone calls, I had to buy another tickets to enable me travel to Dublin from Manchester. I want my money to refund.

Rude check in staff. Split family up with young children.
