No PMs, so I'll try just posting the questions here?

Do you have any say/preference in the aircraft you are hired into?
Is there some kind of seniority system?
How do you bid for trips (I.e. Pbs, etc...)/do you have any say in where/when?
Are you ever on reserve?
Is there a way to fly for more money (I.e. Picking up a trip)?
The range on the a/c is about 3,000 miles. Is most of the flying in N. America?

Thanks.
