...Such poor, POOR customer service by Frontier!! And now, they are funneling all calls into that same phone center. Good luck trying to get any satisfRaction from a farce of an airline..


Worst customer service in decades, a total insult to public due to the enormous wait times. The robot skips waiting queues, tells you that someone will call you back in the given time, but it does not happen. I could not talk to anybody at Delta Reservations for weeks, regardless of time or day...

...The service rep had to put me on hold to get authorization for a courtesy waiver of the cancelation fees. Are you kidding me? Like they would even consider charging a fee because they canceled half of our trip??? We re-booked on Delta Air. I see no reason to ever book on Frontier in the future..
