Looking at DEN-SEA versus COS-SEA in April. DEN is $59 and COS is $77. If you are flying from southern CO, definitely worth the $18. Driving would be $30 of mileage, parking would be more, and time behind the wheel.
A premium of $100 one way and I'll drive. $50 is about the crossover point.
18 bucks is well worth it once you figure out gas, tolls if you take E470 out there (that is 20 bucks there) and the higher parking prices. I'm like you, 50 is the point of seriously looking at things. I think landing fees here may be lower (or they are cutting them for it to be attractive). I've been hearing/seeing others discussing new routes and upgaging to make things more attractive.
Also of note, recently the airport just purchased more land as well, there is plenty of room to expand. https://www.fox21news.com/top-stories/c ... expansion/
The 17/35's are 11000 or 13500 (primarily used runway is 17L/35R and is 13500 feet) and 13/31 is 8200 feet long (primary military ops). Even if ops were to significantly expand there is plenty of capacity and capabilities. 35L, 35R, 17L are ILS and RNAV, 17R and 31 are RVAV only. In the 20+ years I've been here I have never seen something land on 13 (most likely due to the pattern it would have to fly to come in).
