The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Love the mosaic program, being able to move to an extra space seat for free is awesome

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

I like their airplanes because they have plenty of legroom in their seats they always work with me if I have a change of plans on my tickets courteous and I always feel safe flying with them.

The flights are back on time and everything else runs perfectly.

They announced at the last minute that international travelers had to checkin at counter. This created a long line and unnecessary stress.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

They switched my flight to Spirit, Never using Kayak again,

i was denied boarding, even though i had an assigned seat, checked in on line and was at airport early. Then they refused to fully refund the the fair and replacement fair because they claimed it was "no show/denied boarding". I will never fly this airline again

Everything went as planned. Crew was great. Seats were still not that comfortable.

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

Was left with many other passengers in SJU by frontier airlines due to delay caused by frontier. Worst experience ever and worst airline ever.

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

It was horrible. My plane was delayed until the next day resulting in me losing a day of work. It’s absolutely unacceptable and I won’t be flying with you any more and I will strongly caution others to avoid your airline as well.

The outgoing flight tpa to fll was seriously delayed due to a frontal system impacting the incoming flight from key west. Weather is not under the control of the airline, better to arrive late than never! Thank you Silver Airways for your caution.

They canceled the flight and no longer fly out of Orlando. Trying to get my money refunded. Lost a night I paid for in Key West.

There was no serving off food on the flight being that it was so short.

The flight was VERY, VERY hot and the blowers weren't cooling it off...don't know what the problem was, but.....otherwise it was fine.

My flight from Avianca was 45 minutes late and it's very complicated to recheck in in ...also I have to say the silver desk folks were neither efficient nor helpful...so I missed my connecting flight. I actually got there before tge flight left but they refused to let me on....and gave me no vouchers for hotel etc

The cancelled our flight 3 times and we never made it to our destination. Every single airplane had a maintenance problem. Never fly this airline

9 hrs wait in airport then flt redirected to airport an hour away from our booked airport. Then at 8:00pm flight Cancelled. Silver supposed to book us on American the next day. Booked my husband but not me. Cost me Ubers, hotel, meals, new ticket and 1 hour taxi Cuz no flights to our home airport. Absolute disaster. Silver staff had no idea what was going on or what to do. Never Again Silver

Nothing about this flight was good. They are always cancelling or grossly delayed. We were delayed for 45 minutes for no apparent reason with no explanation or anything we could see and I missed my connection to Durham NC. I was on my way to my best friends memorial and funeral. Now I'll missed them both!!

Total disaster! The easiest flight was kept delayed till … cancelled! And before official announcement of the flight cancellation I was offered to join ongoing boarding to FLL so I had to change all my traveling plans, have lost my car reservation and a payed spot at the meeting I was going for to begin with! I had to no show to my flight back, because it was from different airport again!

The worst experience we had traveling. The worst experience we have had traveling. The service is lousy, I will NEVER choose this airline again.
