I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

Very dissatisfied with spirit airlines after buying my ticket's they cancelled our flights with no reasoning.

Not good. No updates regarding the flight status until after the fact on the delays and then a cancellation.

We had a 5 hour delay, which resulted in my arriving at my final destination at 2 am instead of 9 pm

Amazing flying experience, even in not the best of weather. The staff made us comfortable and the flight was actually pretty smooth.

I was surprised by a mandatory bag charge when I checked in at the airport. "Carry-on" wasn't an option eventhough all that I had was a small pilot case. I paid $79 so my bag could fly with me.

Loved staff help @ kiosk, staff on airplane. Commitment to punctuality. I sat in a "blocked" row, where the middle seat had no passenger & loved it! I appreciate not having to pay for water, which I've experienced even on international flights. Only negative was how dirty the bathroom was for a 4.5 hrs flight. But I don't think flight attendants monitor this.

It wasn’t a bad flight just very uncomfortable seating wise.

Did what they needed to do. Brought us from point A to point B timely and without issue. Boarding through deplaning smooth.

Atlanta airport gate area floor and nearly all seats disgusting. Spirit airlines crew fantastic!!

The reps working at the airport counter were dumber than a second coat of paint.

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

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

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.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

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