Sports Photographer trying to start aviation photography as a hobby

Hello! So I’m a sports photographer for my actual career but I want to try and start doing some aviation photography as a little side hobby, getting to use my camera more you know. But my problem is that I personally don’t know where to start. Advice is very much appreciated. I’ll be heading to Arizona in a few months for college too so I’d love to hear from some photographers down there if there are any cool spots to photograph planes from Sky Harbor.
