Frontier likes to promote themselves as being a cheap airline to fly, but in the end, that’s laughable. Only AFTER I booked through you, and then had to go to their site to choose my seats and baggage, did I find they charged a $75 “Passenger” fee. No explanation on what that was even for. Then for them to charge $5 for sodas, and who knows what for any small snack, is just insulting.
