Hello, student pilot/aspiring airline pilot here. I have a question regarding aircraft bidding. Say you are hired into DAL flying an A319 and you decide to fly that aircraft for 30 whole years. After 30 years, you bid to fly a B767. Obviously, you’d have enough seniority after 30 years to fly this aircraft. My question is, can you automatically become captain and get the routes/base you want, or do you have to start as first officer with minimum seniority for that aircraft type and work your way up?
