As an addon to my first post-
No. Corporate pilots don't get jumpseating or travel benefits, nor are they CASS or eligible to participate in other airline programs such as FFDO. Depending on the company though, there may be company provided benefits that airline pilots don't have, such as:
Company Cars
Profit Sharing
Cash Bonuses
Stock Purchase Programs
Personal Days/Company Holidays
Hotel Points/Aviation/FBO Rewards (AvCard/Atlantic Bucks/etc)
Expense Accounts
Personal Use of the Company Aircraft
Paid Trips for Spouse to Accompany on Flights
Better Retirement/Pension Benefits
