I have a question about pilots being locked in one base.
So say that I was based out of Miami flying long-haul aircraft, would I be able to bid for a flight out of Los Angeles, or would I be restricted to just flights out of Miami?
Depends on the airline. Some allow it, others don’t.
You would never be able to bid for flights from a different base than your own, but you might be able to pick them up last minute. Of course you would have to get to LAX in time.
