The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Flight was delayed one hour. Notification to the crowd waiting near the gate was terrible…announcements were unclear and very hard to hear and therefore understand. Frontier does NOT send texts to notify, only email. The reader board over the gate itself was NEVER updated to indicate the gate had been changed. It’s like a bunch of children are running things.

I’m not gonna fly Frontier Airlines because booking is not an option. No water or food is for high price, not equipped for health emergency incompetent crew for emergency services. Cheap airline shows it is cheaper in all service categories. Boarding is the best of all airlines!

We’ve all seen the YouTube vids of out of control passengers. But this was an instance of a highly aggressive, bully flight attendant. Yelling in the face of a vet with PTSD who was texting their family. And no , we had not yet been instructed to put our phones in airplane mode. My suggestion is that you should pay whatever difference there is in order to avoid Frontier airlines. Additionally, after 3hrs trying to get customer service frontier offered a $25 voucher. I declined. This experience was so traumatic. To be verbally assaulted and abused by a flight attendant that has the power to say “boo” and I miss my flight ( which was to a family member’s funeral ). Frontier is unsafe and I cannot impress enough how much I discourage anyone ( esp those with any kind of disability like PTSD ) flying on Frontier.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

Overview of Frontier

Focusing predominantly on domestic travel within the United States, Frontier flies to smaller regional locations as well as large cities. Controlling operations from a hub in Denver, the airline reaches more than 105 locations across the United States. Services are also available to international vacation destinations in Mexico, Jamaica, Puerto Rico, Canada, and the Dominican Republic.

Frontier operates as an ultra-low-cost carrier with competitive prices and direct single-leg trips. Fares are kept low by sacrificing luxuries, such as in-flight entertainment devices, while meals and drinks can be purchased as extras. It is a subsidiary of IndiGo Partners, which also controls JetSMART, Volaris, and Wizz Air. A codeshare agreement is held with carrier Volaris, expanding the possible connections between Mexico and the United States.

It is possible to sit in either Economy or Stretch (their version of Premium Economy). The chairs are not designed to recline, meaning the person in front of you won’t encroach on your space. Seats in the Stretch section have roughly an extra 5 in of legroom and a large pull-out tray that is ideal for working on a laptop.

Exclusively Airbus aircraft are chosen for the fleet, with Frontier preferring narrow-body jets like the A320 family. One of the most commonly flown models is the A320neo, which has tremendous fuel efficiency and can carry approximately 186 passengers. The planes have distinctive animals painted on the tails and are all unique images. Among the animals featured are rabbits, dolphins, bears, sea otters, and penguins. The names of the characters appear underneath the cockpit windows.
