plan_B_workz,
I have a few friends who are 32 years old, with no flying background at all when they started their cadet training. So I think being 30 years of age is not such a big deal. The important thing to know is what you will be going through for the next 3 years of training, during which you will spend most of the time away from your family. So, you must be able to convince the interviewers that you are able to juggle your life, with plans on how to handle your family matters both emotionally and financially etc, and that you are able to concentrate on your pilot training. You are going to need all the motivation and focus you can get for ATPL groundschool as well as flying. The last thing you want during training is distraction. All the best!
