Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

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

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.

Friendly staff, It was the first flight out for our plane, so had to be deiced from the frost. Only delayed a few minutes,

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
