Frontier's Go Wild pass has changed the way we travel. I've taken 2 trips so far this year and have 4 more planned. Before committing to the purchase, check the routes of your home airport online free via Frontier's site.
1) Enter your Route
2) Specify Go Wild Rate, vs regular
3) Find a nonstop or preferred route
There are other websites that do more comprehensive searches for free but I find Frontier's to be easier if you have a specific route in mind.
