Frontier Airline Watch the bait and switch Phoenix Az Arizona

Frontier airlines up sells services on flight reservations they know are 'missed flights.’The website enables seat selection and also offers hotel reservations to be made at a discount on flights you will not make any time soon. My new arrival date is 2 days 2 overnights later.I made my upgrades in route to the airport. They issued a "no show” on the ticket. If they are closing the flight the website should not allow additional charges. Also,I would suggest they make false claims on their voice messaging. They say you can change your flight on the website for free but you cannot on a missed flight. Only customer service can do this for $25.00. They will then be so kind as to offer you another change fee $99.00 additional charge fee. Arrival destination whenever 2 days later. Ok so let’s add this up for this low cost carrier $209 one way ticket plus 77.00 seat and one bag.129.00 per night hotel charge x2 . $ 25.00 poor customer service fee. One way ticket $ 569. 00 one plus a lot of hassle. What a racket! Delta courtesy change fee 0 . 15 minute change at the counter. Next available same day flight.
