Spirit Brings Low Fares to Denver

Spirit Airlines is launching Denver service to irritate Frontier, the newest ultra low cost carrier.  A benefit to me is Spirit is bringing super low prices on the DEN-ORD route.  The incumbent carriers aren't even close.  I really hope the Southwest Effect happens and United lowers their fares in light of new competition.  If not, $170 savings might get me on a Spirit flight.

Look at that low fare - or  - Look at those two high fares
