PDT has a lot of room for growth. Depends what you want. I came for the fast upgrade and the PHL base made sense for me. If you want to be a sim instructor that’s a possibility as well as many other roles. If you want to upgrade quick but don’t have 121 time you may need to consider Envoy or someone else because between the slow training process and the extremely slow schedules here it’ll take you a very long time to upgrade.
