I am not really which choice that I would make in your place. However, I will tell you that I am happy here at PSA. It has been a little stressful lately with all that is going on, but I am optimistic that things will work out. The info above about the flow through is not correct. While the final details of seniority integration have not been finalized, there will be a 100% flow through to mid-atlantic from the WOs. You will not have to interview at mid-atlantic or mainline to have the job. You will also keep longevity when you flow up. So for example, I have been at PSA for 2 years. If it takes me another 5 years to flow up to mid-atlantic, then my first year there, i will be makin 7th year pay. It really is not that bad of a deal. And in reality, not many of our senior people will choose to flow up. If we get jets, then they will be making a very comfortable living here with good schedules. I dont believe that they would flow up for an extra 20 seats. So with an integrated seniority list, it is just a matter of time. You will have to sit at a WO for a while, and Mid atlantic for a while, and you will have a job at mainline one day if you are young enough. And even if you are not young enough to flow up, from what i hear the Mid atlantic pay will be tied to the top 3 regionals.
I am just trying to give you some information so you can make an informed decision. I think the best choice is the first that offers you a job...Either place will be whatever you make of it.
