You can fly anything, subject to any type rating requirements. That's the tricky bit. With 150hrs on a CPL you, along with everybody else in the same boat have only scratched the surface as far as the airlines are concerned.
Most people who do not get direct entry into an airline(some do, keep trying) bite the bullet and go and instruct because the airlines want hours.......and lots of them. You can instruct, para drop, do aeriel photography, anything, for anybody to get hours. Then they start to look at you as you start to stand out with 1000hrs.
Good luck.
