From the DELTA WEBSITE:
As part of our Ready Reserve program, you can work 300 - 1300 hours per year. This position could be the perfect entry-level position though, which could eventually allow you to apply for a full-time position if you so desire. The benefits include flight privileges and working flexible schedules.
It may be station-specific but I was told at my interview 1) bidding of shifts is by seniority - what you end up with is what you'll be expected to work, and 2) you can only shift-swap with other R/R personnel...no p/t or f/t'ers.
5 days/week, a minimum of 4-5 hours/shift.
For someone who goes to school or has another job to have the benefits the R/R program doesn't offer, it could be a real problem if you get a line you possibly can't work.
If there are stations out there that has flexibilty on schedules, not necessiarly by seniority bid, I'd be curious to know. Also, stations that don't have 5 days/week work schedule for a R/R. (feel free to PM if you want)
