Airlines don't like it when someone resigns from training. It might reflect a willingness to give up when things appear to be going unfavorably whatever the reason might be.

I'm at my third airline as a pilot and fourth overall. I left my second piloting job because of QOL issues...poor commute and didn't like the airplane I was flying. If you express your concerns at your next interview the way you did here, you may be okay. Leaving an airline due to concerns over its financial viability is valid.

I was upfront during my interview about my desire to leave my current employer. I didn't bad-mouth them, just said it wasn't a good fit.
