Hi!
In training you also get perdiem...about $55/day.
You are airlined to/from your Gateway, to wherever they want you. You can request Alternate Travel to airline to/from somewhere else besides your Gateway. You will probably airline on your last day off. You may be airlined back to your Gateway up to 2-3 days early, if you are in a location where airlining you back to your Gateway will not work on your last day, and the co. does not want to pay you for your "X" days (days off).
It is VERY random, so plan on airlining on your days off. You will then be happy when you are home more days than scheduled, due to the schedule and/or home reserve.
