You can pick up open time in any base.

As stated above, jr capt is around 900. We are upgrading ~25 a month at this point with 1500 on the list. To move up those 600 spots at 25 upgrades a month would be 24 months.

If you just go off the midpoint of the 1500 it would be 750 spots to upgrade or 30 months.

We will be losing 15 a month at minimum just to Delta. Add in all those leaving for United, American, and everyone else...

If Endeavor can continue hiring more than we lose off the top then there will be even more upgrades to cover the added flying.
