CMM92,
Hope you are well.
Sounds like you are in a similar position to myself. I am currently working on my PPL, via a modular route. Studying and learning to fly in my free time, when I am not at work.
I strongly suggest getting the Initial Class 1 under your belt. It’s a big investment, but will honestly tell you whether you have a standing chance to become an airline pilot. It’s better to get this done first, than further down the line after investing so much in your hour building etc.
I’m more than willing to chat over DM. Drop us a line.
Best regards.
