Wow, I am guessing the TPIC crowd is playing with an old deck of cards and doesn't work for AMF. TPIC is not a requirement anymore.
Most all 121 minded AMFers go to a regional after AMF anyway, even with that glorious TPIC.
Now if you are 135/91 minded AMF can help you get on with some SoCal operators.
Some have left AMF for alliegiant, but that was after seven years. You are just as competitive as a seven year fo, which will most likely be captain seven years from now barring a world melt down.
QOL is much better at a regional. Airlines are like a part time job compared to the split shift hell that is AMF.
