If it comes down to a choice between an aviation degree and a non-aviation degree, I would personally go with the non-aviation degree. It’s better to have a backup in case your flying career goes down the dumps.
In the case of getting an interview/job, all the airlines look for is that you have a degree, period. Flight time and experience is the biggest criteria that they are looking at, not if you have a degree in aviation management or biology.
That being said, if you are planning on making a career out of the aviation industry having a degree in something aviation related may help you with getting a job.
