The worst flight of my life. Never will I fly frontier again

Landing in terminal 2, but my luggage is terminal 3. We (and others) were looking for it in terminal 1. We probably missed the crew broadcast, but the communication could have been clearer for non native (or elderly) passengers.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!

Bag should not be so much money. This is how Frontier takes advantage of customers

The plane was comfortable. The time to board was way too slow and very unorganized! The crew was not as friendly as normally. The was not a single time that they offered water nor anything!!!

They switched my flight to Spirit, Never using Kayak again,

i was denied boarding, even though i had an assigned seat, checked in on line and was at airport early. Then they refused to fully refund the the fair and replacement fair because they claimed it was "no show/denied boarding". I will never fly this airline again

I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.

This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.
