PHX will most likely be available in training, but you would fly more and be able to hold a line much faster in DFW. The most junior person awarded PHX CA has a November 2023 hire date.
An ALPA rep told me that PHX isn't expected to grow much past the 36 hard lines it has in March. A company email of projected lines of flying shows 30 PHX lines in April, 31 PHX lines in May, and 36 PHX lines in June.
