The staff was fine in the fly, but to do check in was very poor the service.

Nothing that I like. Old plan.. old seats without maintenance. The recline seat in front of me (my was 10F) was 3 inches before my nose. It was not enough space to keep cell phone in hands. Even before landing the cruel does not pay attention to it. The worst flight of my life.

Booked my seat several weeks before and they changed it without consulting me to sit a whole family in the row sending me 15 rows to the back side, not caring if i have a short connection or any other urgent issue. The land crew made some silly excuse of a need to balance the plane because of the few passengers of the flight. Being a priority passenger it felt really a rude and careless attention from the airline

Friendly stuff , enough leg room in economy class, very efficient boarding and take off on time. There is no place to charge devices and movie collection is not to my taste. 9 hours of flight went very easy.

Very comfortable aircraft, plenty of room in the budget class. Especially liked 2 rows on each side with a 2-sitters. Staff is helpful and friendly. Food was actually very tasty. Negative- no self service electronic check-in counters which make the line much longer than could have been otherwise; outdated entertainment screens with limited choice of movies . Otherwise our experience was very pleasant and 9 hours passed without difficulty

They landed on the correct airport-no last minutes changes. Often times you hear of flight going to EZE but being diverted while on the air to AEP. It was crucial I landed in EZE as my international flight our of Argentina was taking off in 4 hours in EZE. Managed to do so and spare time to enjoy a coffee.

Old Plane with a broken seat. No food on the plane

Luggage is limited and the process for payment is convoluted. The crew is racist. Questioned why we were in upper class

My flight was cancelled over technical issues. They moved passengers to other flight that departed a few hours after mine. They left us for the 330 am flight (the original flight was 19:40). We went down the tiny Salta airport to grab dinner and suddenly they fixed the original flight and left, and never told us or made the announcement. It´s a really small airport, they could´ve looked for us, but didn´t. The flight took f with 8 passengers. And we got home after 6 am

There is no phone charging port on the plane. The infotainment system screen is small. The seats are very uncomfortable.

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

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!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

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

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Plane never left the ground. Mech issues - entire trip was rerouted through united.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

I liked everything, this was classed as premium economy but it was much better than Lufthansas business class. Lovely staff, comfortable plane and an excellent seat arrangement. A very pleasant surprise.

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

Staff encountered friendly and helpful. Flight delayed 1 hour due to mechanical issue, but made it through Atlanta immkgration and security in plenty of time,

This airline scams people into paying multiple times for their baggage. I prepaid $150 for my son's baggage roundtrip from Miami to Cusco. We he checked in at Miami, they said it was not paid for in their system and they would not let him board the plane unless he paid $88 for the baggage despite him showing the receipt that I had already paid. THEN, when he landed in Lima, they told him he had to pay another $73 for his bag to get to Cusco or they would not let him board...even though he now had 2 receipts showing he paid! I called to let them know of this error and that I wanted to be refunded for the additional $161 they charged him. I also wanted to make sure that it was showing in the system that we had already paid for the baggage so that this would not happen again on his return flight. They assured me it was in the system, but when we went to check in for his return flight, they said it was not in the system (despite me showing all 3 of our previous receipts and where it had come out of my bank account) and made us pay another $73 for his baggage or they would not let him on his return flight! I have called twice and emailed twice with no resolution. We paid $384 for one normal size and weight bag. They did the same thing to my mom on a flight the week before! I truly believe that they are scamming customers out of hundreds of dollars. I would like to know what agency I can report this fraud to as trying to address it with the airline has not worked.

Disorganized. Multiple flight time changes both ways and double dipping charging for carry on bags/checked bags. We booked directly through Sky to avoid 3rd party agent hassle. Unlikely to fly again with this airline.

Changed schedule without notice , canceled flight, mediocre competition, no help with the lost connecting flights.

Bare bones flight no entertainment minimal, if any food or beverage. warm beer only if you want a cocktail

Sky canceled our 8 am flight at 1 am. However Kiwi.com, who we used to book our flight (because sky airways online system would always give us an error message when we entered our payment information ) didn’t claim it was a cancellation but simply a 12.5 hour delay, and rescheduled our flight for 8:30 pm. This would have left us stuckk at the airport for 12.5 more hours, as we we staying at the Wyndham hotel at the airport. We were unable to request a refund this through kiwi because they don’t allow refunds for any schedule changes with less than 24 hours difference. Kayak and sky airline’s own websites showed the flight as cancelled. Only kiwi showed it as a very very very delayed flight. This way kiwi can keep our money. Ugh. We tried for hours to request a refund at the sky airlines website, but there was always an error at the very last step where you enter your refund credit card information. We ended up being forced to request refund vouchers which are good for 12 months but which we will likely never use. We ended up booking new flights with Latam airlines that got us out at 8:40 am. We will never use kiwi.com again.

my flight was canceled without reason or possibility of resuming another flight within the time frame of my trip I could not contact an adviser either by email or by telephone because no communication possible on the website I could not have the flight reimbursed I find this way of doing things by the company inadmissible I have lost €250 it is theft I do not recommend this company and I consider that you have not done your job because I have not obtained any help from your part

J’ai réservé avec Kayak. Sur mon billet de confirmation il était noté que j’avais droit à des bagages pour chaque passager mais on m’a fait payer 36 dolllars pour l’un des passagers.

Flight check in Lima to Cusco all went very smoothly and plane boarded on time. All in all a great experience for a low cost fare.

Don’t ever book with them. They are worse than Ryanair and you will end up paying more for the worse possible airline and deal with ignorant people who don’t know what “customer” is. Avoid at all costs
