My line award next month was initially just 72 hours. Not a lot of pay.
There is a small window before each month starts that I am allowed to trade my trips around. I did just that.
I traded every single trip for a new one. New line value is 86 hours.
It wasn't easy as I still had to work around day care for my daughter and time with my family. I didn't lose any days off though.
A buddy of mine built his line from 76 hours to 99 hours and 30 minutes....but lost 3 days off. He has no kids and a very understanding wife. I'll see how sane he is after July.
