Now that PSA has finally quit most of the bonus games, and raised the Captain pay to a respectable level, I don’t see ZW being competitive.
Regardless where you choose to go, knock your Bachelor’s degree out while your sitting reserve, or sitting in hotel rooms. At the current rate of flow at PSA, you’re likely to be there 8-9 years before your turn to flow arrives. There’s no point handicapping your competitiveness elsewhere because you can flow to AA in 8-9 years.
