Ok, how’s this:
Nobody knows.

In all likelihood, LAX will get some vacancies as the whole system has to absorb all the new hires. Will you be able to hold it? Likely, but not definitely. Will you be able to hold Denver? Unlikely.

Based on what has happened in the past, just about any base has eventually been attainable due to system growth and movement. Bases that have shrunk significantly (DEN/ATL) notwithstanding. Give it a few months.

People are understandably a bit jaded right now due to the past couple of years and are projecting their frustrations on the question. There are some really junior pilots in LAX. As the system goes, it’s one of the more junior bases. Fair enough?
