Though I am an actor and I work in a world of fantasy, I am also a teacher and demand "the truth".
Frontier airlines is a lie. Border lining on Fraud and misrepresentation, I advise anyone looking for the truth to look elsewhere.
Like the other demon Airline "spirit", your flight charge is à la cart includes nothing but air and possibly the toilet.... Possibly.
Your carry-on bags are $40.00 even if they both fit in your hand.
Good Seats are unavailable without an up charge and you must be a 5 foot one Asian man or woman to fit comfortably in the seats.
As a person who travels often with smaller Asian people even they complain!!
So there's that.
Find yourself a new frontier and go elsewhere.
