I'm 100% with Lovzzin on this... Keeley, if you commit the next 4 years on your PhD and then take 18-24 months getting your fATPL.... you could well miss the bus!
Your existing degree is helpful and positive but not essential... how much better will your recruitment chances be with a PhD? (Respectfully I'd say none!)
During the next 12 months alone you could be working and paying for your PPL, multi, night rating and (perhaps) IMC ratings. That would place you much higher on your aviaton career ladder than you will be in 4 years time with empty pockets and more debt!
Good luck anyway bm
