The company doesn't have chosen ones. To them it's like paying for a part. Why buy another one when they the one they already paid for is working fine. They already paid for the pilot to be trained.....why would they want to train another if they don't have to? Managment looks at numbers, metrics and anything they can measure. To say they prefer one group over another is plain silliness. They treat us all as cost centers and replaceable.

If your seniority can hold captain 737 then bid it. Between new aircraft deliveries and retirements there will be plenty of vacancies.
