I'm a junior DFW FO. I move up 2 to 3 numbers per month due to upgrades.
We were upgrading about 14 per month systemwide this year. Oct we are upgrading 24 (3 from DFW). Don't know if that is an outlier or a trend. I understand there is virtually no movement for Captains in DFW. As soon as someone is about to advance a #, a moderately senior guy trades in from another base. We also have pilots leaving for greener pastures. I would imagine one per base per month. 1/4 of my class left with 1 year.

Regarding the no growth comment.. We average one new plane per month through 2021. 104 on property now. A couple deliveries have been brought forward from next year to later this year. 147 WERE on the books for the end of 2021. That number has increased to 160 without placing another order. We staff each plane with approx 8 Captains and 7 FOs. You can do the math on your upgrade potential. We are currently upgrading in the mid 900s seniority. The last guy I see on the recent vacancy award is #1735. There are well over 100 FOs in DFW and today you would have to be about sen #15 to upgrade.
