No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

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

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.

I paid for the service of having the right to choose my seat and it was not like that, they put me where they wanted and I explained to one of the staff that they were before boarding and they were very rude. I am traveling with the family and they put us in separate seats.

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.

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

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.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

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

The worst flight of my life. Never will I fly frontier again

The plane was comfortable. The time to board was way too slow and very unorganized! The crew was not as friendly as normally. The was not a single time that they offered water nor anything!!!

The plane failed preflight inspection, so we sat there for 90 mins while they tried to fix it. Ultimately, everything was remedied and we made our connecting flight; instead of a 2 hour layover at the airport, we spent it waiting on the plane.

The check in process was a mess for no reason. I spent an hour waiting in line trying to get them to print my boarding pass and as a result I missed my flight.

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

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.

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.
