well...I'm no UPS pilot, but from what I know...
No UPS pilot or any pilot would fly 1 day out of 3 weeks...and I highly doubt that any airline would make money if they had 3000 pilot flying 2 days a month...so the answer to that questions is a no. The only exception would be if she just used some vacation time during that month...but still not very likely.
I know that website that you are talking about... pilots are able to remove their names from that website if they don't want it to appear...so not ever pilot will show up there.
Any pilot can live anywhere in the nation as long as they are willing to commute. My brother is based in Seattle but lives in Medford, OR. I know one Air France pilot that lives in Germany because he likes it there, but is based in Paris. So they don't really need to live near a hub.
If you ask for my opinion...I think that everything is normal except for the flying 1 flight every 2 weeks.
