Frontier Airlines EarlyReturns (Pre-Alignment) - Interesting out of STL

I'm not an F9 flyer but being in STL I keep track of fares out of here and noticed that F9 has been filing fares to the east coast and Florida with flights via DEN. So, if you've got a lot of time you can fly STL-DEN-LGA-DEN-STL for $175 all in. That is almost 4,800 miles. Similar options exist to Florida.

The Classic Plus price is only $145 each way, which given its flexibility is a good deal for a refundable ticket.

May not be a very bad deal, for someone on a MR..

I heard an ad on the radio today that YX is starting up STL-MKE 3X daily on April 1, 2010.
