I am currently in training at an airline and I will not be in Cass until the end of training. Can I non rev on Spirit without CASS?

I take it you will have a company ID?

Correct I have an id

You should be alright, call and list yourself ahead of time. Then find the captain just incase you have a problem. Our manuals say you can have a seat in the back but alot of our gate agents aren't the quickest.

Also assuming you have an agreement with us.

Im pretty sure you're a 3M (Silver) employee? If so, we are in CASS during training, just no actual cockpit access, you use the cabin only access. You get non-rev listing on CAL, and jumpseat on all airlines we have agreements with. So far, Southwest and American have been tested and confirmed. When you list, I believe it is still under "Gulfstream International Airlines."
