You are in a good position to tell.

I would think so; hiring and recalling 2,500 FO, you would think half of them would go to backfill upgrades to CA, even if it was all growth. (Half CA and half FO for increased flying.)

In reality, a good chunk would be backfill for retiree CA. That would make it even more than half of 2,500 as upgrades to CA.

Maybe 1,500 to 2,000? I would appreciate anyone having the data, rather than me making an educated guess.

2,157 new hires 2014-2017

Trying to find out the 2013 recall numbers.

CA upgrades looks like it was close to 1,300. (hard to figure out and the SLI number jump makes it more difficult to tease out of the data)

For an estimate made five years ago it seems to be pretty close.

What's more junior right now, 777 FO or 737 CA? If you bid over from 737 FO to 777 FO, what's the seat lock time before you can bid 737 CA? I'm guessing the most junior base is NYC for both, followed by MIA?

777 FO is more junior. But, by how much depends on the base. It's about 1800 numbers in Dallas, but only 500 in LGA. LGA is more junior at 737 CA, but about the same as MIA for 777 FO.

Seat locks are waived after 6 months if you're upgrading.

Junior 777 FO is 11,781 (LGA). Junior 330 FO is 11,945 (PHL). Junior 737 CA is 11,082 (LGA). There are about 14,500 pilots on the list. If you bid 737 FO to 777 FO, there is no seatlock to bid 737 CA. So you could try out the 777 and if you don't like it, bid 737 CA.

It’s not necessarily a SABRE thing, because when I was at the old Eagle, we could grab any portion of a trip in Open Time. I did it often.
Was more than a bit surprised at some of the contract holes when I showed up here on LAA property. Quite a few, actually.

You always get a two-year seat lock in. However, for your first upgrade to Captain, you can break an existing lock in after six months.
