1. The first couple days of class the union (if you have one) will introduce you to your carrier's contract. If your contract only covers your regional and is not the same contract the parent company pilots work under, you are not a legacy pilot the day you start class.
2. The first couple days of class HR will have you sign up for the company's 401k. If you are not receiving something north of a 12% direct contribution without a requirement for you to contribute while the parent company pilots are enjoying that direct contribution, you are not a legacy pilot the day you start class.
3. The first couple days of class you will probably bid for an aircraft and a base. If the only aircraft available to you have 76 seats or less, you are not a legacy pilot the day you start class.
4. The first couple days of class you will have access to your seniority list. If it doesn't include all the pilots at the parent company, you are not a legacy pilot the day you start class. Furthermore, if you are hired at Regional Air today, and I am hired at Legacy Air tomorrow, you are not a legacy pilot the day you start class if when you flow to Legacy you are not a higher seniority number than I am.
