The wife and I want to attend a wedding in April in Colorado Springs (COS). We live at RDU. Right now the cheapest flights to COS and Denver(DEN) run about $300 each, which is too much. I'd like some advice on this situation.

1. Do we expect fares to go down once ski season winds down? Will I have enough time to get a flight at that point?
2. Is there some deal that I can get a companion ticket by applying for some credit card or something?
3. Any other ideas I'm missing?

I think $250 each would be more appropriate for either COS or DEN.
