Current UAX non-WO FO here!

As part of my Major Research, I just wanted to get the most current and reliable way to get ORD as soon as possible out of training. Tracking the NH drops, looks like going the 737 route seems to be the quickest?

For reference, I'm expecting to be the 8-ball in class. Would that push me towards WB EWR and away from a vacancy/base trade to ORD?

What about 787 in ORD? What kind of hire date are we seeing on ORD FOs? Thanks!
