(Shameless plug for UA despite the stupidity of the current TA)
Did anybody mention that the junior lineholder in July in the entire company was a LAX 737 FO (2 months on the property, so not even a full month on reserve) and Captain bids in LAX have been going unfilled (can't bid on those till off probation). So, your seniority movement at LAX is currently unbelieivable on the UA side.
