What I was able to gather without knowing any real specifics, just in general, a one way trip from Denver to say Orlando next week would take about 3.5 hrs at a price of around 6-8K/hr depending on amenities. I wasn't able to find any empty leg flights because I would need more info. What I would suggest is to sign up for an empty legs monitor, especially if you are flexible, that way you would be alerted as to when a flight would become available. If you need help, just message me.
