It's a simple one page document. It asks questions you answer and send back. It's that simple.

They ask if you have anything that will interfere with your invided indoc date and flight training "for a period of at least 90 days from the start date of my new hire class". . . .Or . . . if you need to defer.

They ask if your first class medical is good to go.

They ask if your info on Airlineapps is correct. If not, fix it.

For military, they ask your current status:

a. Currently retired or separated?
b. Going to be and on what date?
c. Active but available permissive TDY or Sep Leave?
d. Guard or Reserves and will remain as such but can make the indoc + 90 work.

Sign, date and email back. Call and make sure they got it.
