I just flew with a junior CA (upgraded Jan 2015) who spent precisely one month in MSP and is now SFO based.

On a separate topic, I just got my first 5-day OBR assignment At least it's in PSP and there's 3 days of flying in the middle. So I can sit reserve by the Renaissance pool.

Although I can't figure it out...SFO is way short on reserves and PSP looks to be almost at its reserve staffing target level. Yet they send me from SFO to sit reserve in PSP? Huh? I'm sure it makes sense to someone somewhere...

And they initially scheduled me to return to my base late at night on Day 5. I saw that this conflicted with policy (they have to get you back no later than 2 hours later than the end of your originally scheduled RAP.) I called CS with the policy verbiage in hand, and fortunately they did not put up a fight and gave me an earlier flight back.

Still, I am utterly mystified why taking a reserve out of a desperately-understaffed base and sending that person (me) to a base with sufficient reserve staffing is a smart use of resources...
