I am ok with the lines like they are and I commute. I probably average 1 overnight stay in base every month because I seek out commutable trips and they are pretty easy to find right now due to the normal ebb of flying this time of year.
I have 127 tfp on my board for Feb (that number will more than likely decrease as I plan on dropping a trip later) right now and only one non commutable trip.
I like the AM/PM schedule. It works well for me as a human.
