Additional routes between okc and den

[fjthornton99]

Good afternoon... I don't fly much so I could use some help.  2 weeks ago I checked flights between okc and den.  There were lots of flights and they were very cheap.  Today I got online to book the flights and all but one was sold out and it was expensive.  Does Southwest ever add flights once they are all booked up on particular dates?  I'm flying Dec. 28, return Dec 30.

Holiday season flights definetly fill up fast and have a limited number of Wanna Get Away fares.  Southwest does occasionally make lower fare buckets available again closer to the date, but it's not likely considering demand for flights is extremely high now and they can sell tickets at higher fares.  Sadly, you might be out of luck on those dates, but never hurts to keep checking.
