RV Parking is $110 a month for those of you considering it. The RV situation has been rumored to end soon because the parking lot is near it's capacity.
Rightbettor,
Yes Apartments are expensive. Expect to pay $1000 a month for something you'd feel safe in. You are correct to assume you will be a lineholder quickly if you stay in Oakland. I was a lineholder in my third month. Also consider that Oakland is a commuter base, if you want to pick up extra trips, Oakland tends to have a little less competition for them. You could pay for your apartment by flying two and a half extra days a month (extra flying pays at second year pay rate, a little better than time-and-a-half). Yes PHX is cheaper, but good luck flying extra there. PHX is Junior and Senior as you described.
To answer the second part of your question. I expect to move up about three to four seats a month once the new hires start showing up. That puts me at the top of the seniority list in 5 years.
