We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

Amazing KLM service and brilliant economy comfort seats. Well worth the extra.

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

Everything in general was great, but we left 30 minutes late

Pros: "Crew was great, on time flight, clean plane."
Cons: "Entertainments options were shockingly few. Honestly have not been on a plane recently with so few and limited options of TV series and movies. I was extremely surprised. Wish I had know and I would’ve had more options for my family."
Pros: "Friendly crew, great access to a variety refreshments, robust entertainment library."
Cons: "No suggestions."
Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."
Pros: "The crew were great! The seats are not that comfortable, it happened that I had 3 seats raw for myself but the armrests were not going up so I could not utilize them and lie down to sleep."

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

Last minute cancelation, though a substitute flight was found I could not pick my meal or seat. The hotel offered didn't have working air control or shower.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

Flight was delayed slightly but was very smooth. It was a short flight but comfortable.

Not worth paying for business class on this airline. The seating is exactly the same as the rest of the plane. Crowded. Horrible food.

Little space and no pad provide for lie flat seats in business, Movies were limited and grouping very strange.

The accommodations are top-notch. The only negative was that both our initial flights were delayed, which caused us to miss one and almost miss the other. The staff immediately handled the missed flight and compensated us for the inconvenience.

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

"I am aware that there was a strike at Munich airport, which led to the cancellation of my flight. Additionally, I had insurance for the flight. Lufthansa informed me about the cancellation approximately 2.5 hours before the scheduled flight while I was en route to Rzeszow airport. They offered me accommodation in a hotel for the night and arranged two connecting flights for the next morning, instead of my originally booked single connecting flight. Consequently, I arrived a day later, causing me to miss a day of work and some important meetings. I hope you can assist me in obtaining a refund for this inconvenience."

Some people facilitating gate onboarding weren’t as cordial. Didn’t feel good about my experience

Online checking, bag drop, ground crew and flight crew excellent. Seats better and more comfortable that many others in Economy, still narrow for 9 plus hour flights, but you manage. Drink and meal service a bit sparse but adequate, return flight was a bit less attended. All in all, a good experience. Lufthansa never disappoints.

I never made it airline cancel my ticket at once, and inform me that I have to purchase new ticket.

They have more than 4 hours delay, and broken all my bags

The full flight boarded early, and then we sat on the tarmac for a long time waiting to get our plane de-iced. The crew was professional and pleasant, and the flight was pleasant overall, albeit slightly delayed. I did not use any of the entertainment options.

Gate agent required us to check our perfectly legal carry on bags due to a supposed lack of overhead space. After seating, we saw nothing but empty space in our seating area. This caused luggage to miss connection in Athens, and we had no bags in Mykonos. Totally avoidable and unacceptable. My last U A flight !

With the upgrade everything was better- more room ,better service and offerings

Everything’s went straight forward, no issues, good service and friendly crew

Ryanair is the worst airline in Europe and easily one of the worst in the planet

The flight was 45 mins delayed but the crew provided water and necessities like tissues

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late

Pros: "Cheap, saved me when I was in a pinch, and easy check in. I loved being able to check in on the app and check my own bag!"
Cons: "It was difficult to understand what the flight attendants were saying over the intercom. Between the masks and the intercom, nothing came across well. Please continue to wear masks, but perhaps find a clearer way to communicate for those of us that are hard of hearing. I was too embarrassed to say “what!?” 84 times. It’s not their fault."
Pros: "Quick boarding and arrived early."
Cons: "The seat was very very small for an average size human and the seat belt was on max.. No social distancing between seats"

Short flight, some waiting to board, but no issues and no frills.

Pros: "Nothing,except I got to my destination safely"
Cons: "Everything.They don’t ever offer you WATER in a 10 hour flight!! Check in crew rude. Attends dismissive to rude."
Pros: "Value for money"
Cons: "Boarding process really needs to improve. There is usually a chaos during boarding"
Pros: "We landed safely."
Cons: "The operating flight was changed and our seat were downgraded. Given that it was a birthday trip i wanted my fiancée to be as comfortable as possible. Instead she was stuck in a middle seat between two crying babies with no outlets to to charge our phones for entertainment. Additionally I was notified that I cannot be refunded until after the flight has landed. So technically Norwegian still has my money and I paid top dollar for a less than average experience. Unacceptable."
Cons: "Need food upgrade !!!! Paying for food and not available or sold out is big No No!!!"
Pros: "Movies and tv were nice."
Cons: "Wifi was so slow i gave up on it and just watched a movie. I flew 10 hours, nothing complimentary. Greedy"
Pros: "Great service, love being able to order food and drinks from the in seat computer."
Cons: "Nothing really."
Cons: "Delays with little explanation of what was going on. Loaded the bus, the unloaded. Should have just had us wait"
Pros: "Very smooth flight with comfortable seats even for low fare customers"
Cons: "I got flagged for extra security, which lead to some extra confusing steps and extra stress. This was compounded by strange behaviors of the digital kiosk (probably related to the security screen), crowded airport, and language barriers."
Cons: "Flight was delayed 5 hrs, gate changed just prior to boarding"
