I was being facetious.
You need 1000 hrs 121 SIC time to upgrade at a Regional.
I don’t know which Major requires what exactly but I’m thinking more 121 time would be a plus over less 121 time.
If your goal is to semi retire at a Regional after you’ve retired from the military I would understand your question.
Doesn’t sound like you do though as you want to get on with a Major.
So I’d embrace the suck for the time that it will take.
