This was my first ever time flying with Frontier. It did not get off to a very good start. Our flight was delayed for nearly five hours. To this day, I have no knowledge of the reason for this long delay. The communication was very poor from the airline. I tried to call and get rebooked on another flight however nothing was available for that day. I also tried to call their customer service and the average wait time was 30 to 45 minutes. Unfortunately, this is the type of stuff you would expect from a budget airline. You get exactly what you pay for and not sent more.

Overall, no major problems and all employees were great. The gate area was not large enough for the passengers, so people congregated in the walkway or sat in a different area, which is slightly burdensome because you can’t hear announcements elsewhere. But this is an airport not airline issue and nothing in the short term could address it.
