Airport staff was terrible, they made up excusses on how I can get to my terminal, I missed my flight then had to pay for A whole other flight! Worst experience ever, even A employee also loughed and said yea sorry for our poor training.

THE BARE METAL SEATS AT THE FRONTIER GATE IN CLEVELAND HOPKINS AIRPORT ARE DISGUSTING...BUT JUST A LITTLE BETTER THAN THE SEAT MATERIALS ON THE PLANE! THE "COMMERCIAL" ANNOUNCMENT PUSHING THE CREDIT CARD DEAL IS OBNOXIOUS AND UNWELCOME! THE VOLUME OF THE OFFER ANNOUNCMENET BLARES LOUDLY AND IS FILLED WITH A HYPED UP, CANNED SCRIPT. BOTTOM LINE IS THE FLIGHT AND THE CREW WERE VERY GOOD EXCEPT FOR THE ABOVE.

2.0 Poor
Maximizing profits is one way to a healthy bottom line, the other is repeat business and referrals from satisfied customers. Frontier has clearly chosen the former. One of many examples: Family emergency required me to cut trip short. Headed to the airport to fly standby for the return trip I had already paid for (yes I understand prices vary with demand etc). Was told there is no standby and that I would need to pay for, despite what it's called by the company, what amounts to a new ticket. And surprise surprise, there turned out to be dozens of empty seats on that flight. To say nothing of the sleazy third and fourth party resellers, the flight/ticket insurance I elected and thought I had paid for that mysteriously wasn't there when I needed it before I left, and on and on with third world sleazy management decisions. The inflight coffee (that I had to pay for) was very good though.

You have to be super careful when purchasing as *everything*, a carryon or a sip of soda, has a fee. They relentlessly chip away at you with surcharges and extra costs … and it’s not always clear what you are getting when you buy your ticket. Will not fly them again. And … crew were not friendly until off boarding .. like they don’t like working for Frontier.

Air was off while waiting on the runway and the temperatures became very uncomfortably hot. Flight attendants were very loud and rude the entire flight.

I booked tickets from San Diego to Cincinnati months in advance to attend my sister’s wedding, a wedding where I was serving as the officiant. At 10:00 PM the night before my 6:00 AM flight (just 8 hours before departure), I received an alert that my first leg to Denver was delayed, causing me to miss my connecting flight to Cincinnati. When I called Frontier customer service, they informed me that they couldn't get me on any other flight that would get me there in time for the Saturday wedding, let alone the rehearsal dinner. Because I had a critical role in the wedding, I was forced to buy a last-minute ticket on another airline for three times the original price, costing me well over $1,000 extra. Even with the emergency flight, I still missed the rehearsal dinner entirely. When I spoke with Frontier, they agreed to refund my original ticket, but showed zero care or accountability for the massive financial burden and distress they caused. Their "compensation" for causing me to spend an extra $1,000+ and miss an irreplaceable family event? A $75 Frontier voucher. Frontier completely dropped the ball. Their customer service showed zero empathy, and their reliability is non-existent. I will never fly Frontier again, and no one else should either if they actually need to get where they want to go. Tip for anyone flying from Denver to Cincinnati: Avoid Frontier connecting flights or layovers at all costs, especially for time-sensitive events. Book direct flights with an airline that actually offers reliable customer support and rebooking options when delays occur.

Their "compensation” for causing me to spend an extra $1,000+ and miss an irreplaceable family event? A $75 Frontier voucher. Frontier completely dropped the ball. Their customer service showed zero empathy letting me know that it was Frontier who was the real victim by refunding my ticket price, and their reliability is non-existent. I will never fly Frontier again, and I strongly advise anyone who actually needs to arrive at their destination on time for an important event to book with literally any other airline.
