Javier, if you can dream it, you can achive it! Your UPS work experience is a huge advantage. If you can accomplish the following, you will get an interview. So let's take this one step at a time:

1- Maintain an impeccable work ethic with your current position. What your supervisors say about you in the future is the key to reaching your goal.

2- Get a 4 year college degree. Get a degree in anything, think of what comes easy to you. What is afordable to you. What is convenient to you. The subject matter is irrelevant, just get a degree. Look into accredited online courses if that is what you can do while working.

3- Get your pilot training and experience. Your training can be done at any local flight school. Look into the smaller airports near you and start flying lessons. Once you have your CFI, you can start instructing and gaining the needed flight hours to land your first flying job. The internship with Ameriflight is an excellent goal to have but first you must have some experience.

Keep your boss in the loop. Let everyone know you plan to be a UPS pilot some day. They will help hold you accountable to your goal. This worked for me it WILL work for you. If you can dream it, you can achieve it!!

Good luck brother, I look forward to flying with you one day!
