In addition to the poster above, few other points to consider:
JQ does a bigger mix of day trips vs VA with more domestic overnights to my understanding. This means JQ is likely better if you live in base, but VA could be superior if you have a long drive to work.
You don't know where you truly stand on VA's seniority list until 2026 when the last of the old crew can still come back.
Can anyone shed light on if the final goal is QF, which would be superior from this angle? Is the rate of internals moving across from JQ lower than those who get picked up from QLink; i.e. while JQ would give you a faster command would it slow you down if mainline was the goal?
