DTA is down at $4.62 per hour from time you sign on to time you sign off for your shift - no other allowances unless you are CPT etc etc.
They said that it is expected that you would do 800 hours a year. So in DTA alone you could make around $3700 extra a year. Not much but it may push you in to the $3100 per month take home bracket.
The bond period is correct - 2 years. For cadets, not applicable because you are stuck there for 5-6years anyways.
I think you hit the nail on the head - multi crew opportunity and big gains.
It's a big step in the door for someone who is willing to walk a few extra hundred miles to chase the dream.
