The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

Some had videos and games on tablets with higher than necessary volume going the whole time.

Ground crew gave me interference about carrying a laptop and a small shoulder bag, even though I told them I traveled with them all the time. I then placed my laptop bag in my carryon and took out a medical device, and ground crew still tried to give interference. I had to remind them that medical devices don't count towards luggage limits. It was quite annoying and unne

The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.

Great flight. Departed early, arrived early. However they were out of meals for sale. Also, we arrived early and the gate was not available so we sat on the taxiway for quite a while (not JetBlue’s fault).

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.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

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.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

TERRIBLE. Cancelled my flight one month before my trip. Have not received my refund back.

Airline is in bankrupt and they didn't communicate it to customers

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!!

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

Both legs of the flight were changed. The day of the flight and length of the trip.

My tickets got canceled on me by your site and I didn't have a flight. Then you kept sending me emails on the status of q flight I didn't have tickets for.

No way to get boarding pass on my phone. In order to print the bag ticket a boarding pass is needed. Asked the agent to print me one, they said they typically do not due this as its so much work. I showed the email confirmation and I asked how i could do it my self the agent replied he did not know as there was no link. The flight was delayed due to an attendant forgetting to come to work. On the flight no drinks were offered only for purchase meals.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

The Boarding process in Denver was chaotic, and since the line was so long, we were lined up very far from the gate. If there were any announcements from the gate staff, we didn't hear them. The flight attendants were spectacular. The only negative part of the flight was sitting by a 2 1/2 year old who was unruly and unfortunately had parents that matched his behaviors. Also, the restaurants in Denver on the E concourse, they didn't have food (passengers could only order 1 item on the entire menu) or the restaurants had 12-14 people waiting for orders to be prepared and another 6 people waiting to order. If you have a layover in Denver and need to grab food, be prepared to visit the shops with pre-packaged sandwiches, or you can visit another concourse but it may take a while to transit throughout the airport.

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

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.

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

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!!!
