Training is at the SLC airport, hotel (double occupancy) and reduced guarantee pay is provided for new hires. No per diem for new hires IIRC. I think you get full pay and per diem after your simulator checkride?
I suspect this will be a Brasilia class, junior base FAT, but SLC, LAX, or other California towns might be possible.
Assuming you are UAL, you get jet FO pay even on the EMB, right?
