If you get assigned the 747- ANC is the most jr. All new hires start there. You can have a good line in ANC within about 3 months after IOE. (IOE wait times can be as long as three months though after your checkride on the 747 side of the house)
PAE for FOs can be around a year to get. You will probably get LAX sooner than PAE though.
On the 767, its CVG and JFK.
