Hi!
To answer the earlier question:
If the House (1/2 of the Congress in the US, the government body that creates laws...the other 1/2 is the Senate) version of this bill stays intact, then yes, BOTH the Capt AND the FO of a Part-121 (Delta, Mesaba, Southwest) will have to have their ATPs, to fly any passengers. That is the FULL ATP, NOT a frozen one. To get your ATP in the US, currently, you need 1500+ hours of flight time.
All new hire FOs, to Mesa, for example, flying a Dash 8, will need over 1500 hours and will have to have their ATP to work there.
