I would say finish your degree. I'm glad to have mine in case the markets go south again. You might be able to get on with a 135 operator in the meantime though so you can do more flying than CFI, although I'd recommend you getting that too. At 280/60 you can get a job, but with some more hours, you can pick which airline you like from the ones that offer you a job. You won't be able to make captain for at least 3 years anyway because you can't get your ATP until you are 23.
