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

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.

Flight was delayed by about an hour, once we arrived at LAX we had to take a shuttle to the baggage claim - it was completely disorganized. The agents at the shuttles were rude and unable to provide any information. Frontier charges extra for everything from bags to drinks - at the end it ends up being more expensive than flying the better airlines

Sat in the airport waiting for my flight for 5 hours. Finally got on the plane only to be thrown off and told that my flight was cancelled. Zero customer service. Nobody spoke to us. Just the worst

3+ hour delay on a direct flight is never ideal.

When I was boarding my departure from Raleigh to Orlando I was inappropriately scolded by a female dog named Mia because I didn’t pay in advance for my carry on bag ($75). Frontiers website is confusing regarding pre-paying for carryons so it was a simple mistake. I also had paid for “upfront plus” meaning me and my son were seated in the front row with no one in the middle seat ($450 upgrade). When we were boarding Mia said “sir, you didn’t pay for your carryon” in a not so polite tone and told me to get out of line and come back to the counter to pay for my carryon. The way they had the retractable rope left me no room to circle back without making the people behind me move so I just stood there and then she said a second time “sir!! Go pay for your carryon” in an embarrassing tone. I then moved their rope so I could get back to the counter when a second female dog then asked “are you done!?!?” because I had said “do you want me to bulldoze the people behind me?” I then said you do realize I paid over $400 for upfront plus so I was certainly not trying to sneak a carryon bag without paying. Long story short, I am soooo done with discount airlines!!! By the time you pay for all the “extras” you might as well have paid for Delta Southwest or American! Frontier airlines sucks and I was embarrassed by a female dog named Mia!!!
