Factors one needs to consider:
Time to command (better at JQ)
Variety of roles (better at JQ)
Desired base (depends on your preference)
Salary (better at JQ, will stay that way under current VA offer)
Days off (better at VA, less so under current VA offer)
Bidding/roster satisfaction (dunno)
Flying A320s vs 737s (your opinion, I have mine)
There's currently not at lot of reasons to join VA. Hoping for everyone's sake that will change.
