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.
W
2.0 Poor
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.

Flight delayed and missed connection. Next available flight was a 10 hour delay.

Ability to choose to board early
T
2.0 Poor
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.
B
10.0 Wonderful
Great flight, no problems. I wish they would increase the checked bag weight limit. Packing was very stressful.
