Dallas is one of our larger hubs and as such you could start your rotation at the Flex terminal at Love Field and end up flying back into DFW at the end via the airlines. You can also get the reverse or any combination of both, it just depends. If you do end up at the wrong airport from where you parked your car, you can expense an Uber to get you back to where you started from.
On the app, we are hiring at 1500+, so you might get a call to do the phone screen. Since you're in Dallas, you might want to attend one of Flexjet's pilot recruiting socials that are held periodically. I think they post them on LinkedIn. The hiring folks look at the entire body of work to date (type of flying matters as they say...) and as well as you as a person to see if you're a good fit within the company culture. I know there were a couple in my class that had the ATP checkride at the same time as their type.
Hope that helps and best of luck to you.
