Had a great flight. Delayed takeoff, but comfortable. Snacks were good.

Pretty seamless, just a tad bit late in taking off and landing.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

Excellent. The lady boarding the flight was awesome. Very efficient, and she got everyone on line.

It was great! The new boeing has much more space and charging ports!

I kept getting h notifications that the flight was delayed. At the airport it was only 2 mins delay. Very confusing. No WiFi on the plan. Snacks very salty. No alternative

I like the boarding procedure. A bumpy ride, but it couldn't be helped. Please make sure the exit seats are clearly indicated.

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Plane and crew on board were fine. Everything else was terrible.

Inbound plane was on time and flight departed on time with no issues while boarding.

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.

My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Better than expected.on time. Friendly staff in NY however MYR not so nice.

Check in online was easy. Seats aren’t very comfortable

Frontier is a crappy airline nothing about it is honest

4 hour delay. No updates or apology from staff. Uncomfortable seats, wonky bad restrictions and up charges, really terrible experience and will never fly frontier again.
