It's good to have plans, but they don't always work out...It's hard to say what the summer will bring. Upgrade times depend alot on how flexible you are. If you can move around you can uprade rather quickly depending on your quals at the time. Ameriflight has a lot to choose from right now so you need to have some time under your belt. Brown and Purple are a whole other story that I can't say too much about myself. I know that there are a lot of pilots who whould like to fly for them. All I can say is chase the dream and stay flexible. Ameriflight is a good company to work for and build good flight time.
