As Hannah mentioned, you will want to renew your passport. As long as you have the Original or a Certified Copy of Government-Issued Birth Certificate as well as a valid driver’s license, you will be good to start training. More information on this can be found here: Preparing for your Airline Career Pilot Program / ATP Flight School
As far as admissions, there is no formal application that you will need to submit. We typically look to see that you meet one of our prerequisites (Admission Prerequisites for Airline Career Pilot Students/ ATP Flight School) but we are able to make exceptions.
After you have called and spoken to one of our admissions coordinators, we will have you start on the steps to enrollment (Enrollment Steps for Airline Career Pilot Students/ ATP Flight School)
As soon as you have your First Class FAA Medical Complete + financing approved (if needed), you are able to reserve your start date. We start every Monday at all 53 locations pending you schedule 3-4 weeks in advance. Keep in mind, you will also have the chance to come out for an introductory flight which is an opportunity where you can meet some of our students / instructors at the facility and get a feel for the training center atmosphere.
Hope this helps!
