It got me to my destination? However we were an hour delayed departing, and we never received any updates or notifications from staff. Poor communication and customer service.
R
4.0 Mediocre
Frontier didn’t give us enough notice that our flight had been delayed. I was just entering the airport when I received the notice, less than 2hrs before my scheduled flight. They delayed it 1hr 22min because another jet left late out of Vegas. Frontier needs better communication with customers because I could have eaten at home and had someone drive me instead of paying for an Uber.

Great flight, no problems. I wish they would increase the checked bag weight limit. Packing was very stressful.

My experience with Frontier was terrible. We were delayed for 2 hours. At one point during the wait at the gate I left to go get a sandwich - I was gone probably 15 minutes. In my absence, they decided to move our flight up, boarded and left. When I came back the two attendants were very rude and I unavoidably had to purchase another ticket on the next flight. During this whole time, the Frontier app did not update the departure time, so I was SOL.

Flight delayed 9 hours. On tarmac for over an hour after arrival. Will never book with Frontier under any circumstances ever again.

2.0 Poor
My ATL–CVG Frontier flight was disappointing due to both an operational issue and unprofessional customer service. After everyone had boarded and the aircraft had pushed back from the gate, we were delayed because the passenger count did not match the flight manifest. The crew counted passengers approximately six times before the aircraft returned to the gate and gate agents boarded to help resolve the discrepancy. We were ultimately advised that a family had been allowed to board but not all of their boarding passes had been properly scanned. This resulted in a departure delay of nearly an hour. I did appreciate that the pilot kept passengers informed and tried to reassure us that some of the delay could be recovered during the flight. My greater concern was the customer-service experience. I am a Frontier Elite Platinum member and was seated within the first five rows. When I boarded, the overhead bins near my seat were already closed. I opened two bins to see whether my small backpack would fit. A female flight attendant sharply told me that a closed bin meant it was full, although the second bin clearly had available space. When I tried to ask whether I could simply place my backpack in that available space, she ignored me. Later, while the gate agents were working to resolve the passenger-count problem, I heard the same flight attendant make jokes about how many gate agents it takes to count passengers. She then made unnecessary comments about the male gate agent doing the count, men thinking they can do things better than women, and women knowing better and outliving men. Later in the flight, she also commented that passengers should know that the first thing they need to do is always be nice to the flight attendants. Courtesy absolutely should go both ways. Flight attendants deserve respect from passengers, but passengers also deserve respectful and professional treatment from the crew. Joking about colleagues who were actively trying to correct an operational problem, making gender-based comments in front of passengers, and being dismissive toward a passenger asking a simple baggage question were unnecessary and unprofessional. I fly enough to understand that delays and mistakes happen. What determines the quality of the experience is how those situations are handled. Unfortunately, the customer-service attitude on this flight made an already frustrating operational delay considerably worse.
