As 5150 points out, degree and ATPL (or any aviation licence) are different beasts. If a job has a general entry requirement of a degree the chances are that the employer is looking for the ability to study and retain knowledge of a complex nature and to have an ability to analyse the info and present structured arguments etc.
Sadly, many employers appear to use it as a way of managing the response they get to a vacancy notice rather than because they are going to use the successful applicant's skills learned during the degree-level study.
But from a practical perspective, if the job is not aviation related it's unlikely that the employer is going to know what is involved with getting an ATPL and it shouldn't be too difficult to hint that studying enough stuff for someone to trust you to fly a B747 around the world is as good as a degree in meeja studies (and I'll apologise now to anyone who takes exception to such comments 'cos they've got one!).
Of course, all this is rubbish if a specific degree is needed......say if the vacancy is for a doctor or something similar.
I'm not sure from your original post whether you mean the job that you wish to apply for is as a teacher. If so, I'm not certain but I think in the UK to teach you either have to have a degree specifically designed for prospective teachers or you have to do a post grad add-on to a first degree to be suitably qualified. I would suggest a call to your local Careers Office - regardless of your age (and assuming they still exist) to see - if not having a degree is a show-stopper. They may also have practical advice to offer about the equivalence of professional qualifications to more commonly recognised bits of paper.
Whatever, good luck.
