Float Pilot V Line Pilot  

Which states do HAA companies like Med Trans, PHI and Air Methods pay over time for hours worked over 40 hours in a work week? 

I'm trying to determine if the extra pay (due to OT paid for over 40 hours in a week), makes a line pilot more profitable that a float pilot position. 

I see Med Trans is hiring more float pilots (80 and counting). I wonder if that is to avoid the OT pay, as their float pilots are based in TX (and dont get OT over 40), even though they work in states where OT is paid to the line pilots.

Do any companies pay the OT for activities carried out over the 40 hours that do not involve patient transports. Ex:- commute, training etc.
