Search Flights From Colorado Springs (COS) To McCarran Intl. (LAS)

They told my son's soon to bride since they didn't book directly with Frontier, their trip was canceled! My son did copy off Frontier's payment invoice so they had to reinstate their trip.Frontier is a horrible company that should go out of business since they do not care about their customers.And to know for hours that a flight will be late and not call pilots down from Denver timely then allow the plane to sit empty for more than an hour is unexcusable.They are horrible. To charge $2.99 for a small plastic cup of ice and small amount of water is hateful.They should have comped everything for all passengers for delaying our flight 6 hr, falling to call pilots timely, charging for seats they failed to tell passengers about when buying tickets,and being just plain rude people.You should take Frontier off your list of airlines that you sell, they give you a bad name.
