For baggage, you'll want 2-3 totes that you can check in when jumpseating, a black carry on, and maybe a small backpack. Totes will hold food, clothes, etc. for your two week shift. I am personally not buying anything like that until I get closer to being on the line. The first few times you head up there will just be training.

They provide jackets/hats/etc, but there is no real set required uniform right now. You may buy pilot shirts/epaulets from them if you want to jumpseat in that outfit, or just wear a nice shirt, pants, dress shoes, and tie. I bought the pilot shirt because it will help get through screening. Not sure how much it cost, but they have a closet full of them that you can try on to make sure you have the right size.

No commitment required. The goal of having SICs in a Caravan is to train us up to be captains of the 207 ($290/day) and then the 208 ($330/day), which normally will take about a year or less from SIC Caravan to PIC Caravan, assuming you fly well and others recommend you. Obviously they understand some people are here to get 1500 and dip out, but your seniority transfers over to Corvus if you'd like to go fly 121 and get paid pretty damn well. As SIC in a Caravan, were being paid more for our first year than most FO's at Horizon, which is pretty crazy.

I originally wanted to go to Horizon or Skywest once I have my 1500, but I am going into this with a very open mind to staying longer if its the right fit for me because so far I am pretty impressed with everything.

Hope this helps!
