There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Not have to pay for every single item to take a flight. Seating and delays sucked.
Terrible. Seats are bad and the baggage policy is inconsistent
Everything was good, and most importantly on time. They have been extremely tardy in some of my flights
They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.
It’s a cheap airline. I wish they had better seats.
The only issues had were outside of Frontier’s control or weren’t expected. It was a two hour flight they completed fast. We landed almost an hour ahead of schedule. The issues with no entertainment or food weren’t issues since there was no expectations. The issue of the loud or crying babies was outside of frontiers control.
Seats are cramped and very uncomfortable. You have to pay for everything and it is too expensive.
Smooth process and flight. My favorite kind. Uneventful and on-time!
Xmas Day- Flights were on time for departure and arrival, baggage check in and boarding process were hassle free, baggage also arrived without any delay. Satisfied customer on this journey.
