yeah, right now the only flying we're doing out of DEN is on the Frontier side which utilizes the 170s on the Republic certificate. So..... that means when you interview, they will put you where they want you: Shuttle, Republic or Chautauqua. In order to get DEN, you need to get the Republic side. And remember, there is no switching over to another certificate unless you are CA upgrading. So whatever you get, you stick with for about 2 years or so.
