To the OP? Get the degree. It doesn't matter what your opinion on the degree is. Nor does it matter what we think.
What does matter is this: although United will hire without the four year degree, to put all of your eggs in that basket would be foolish. If you can find the time and funds to knock one out, that's what you should be working on.
And I say this as somebody who won the lottery and was hired without the degree. I was beyond fortunate to get the interview - I had a lot of ancillary qualifications that helped explain and take the place of not having the degree.
Don't be like me. Get the degree.
Capiche?
