5. “Sufficient qualifications” means the requirements imposed by law and this PWA to enter training or serve as a pilot for Delta Air Lines, Inc.

The PWA has no hour requirement, does it?

The PIC 121 requirement is all that I see that would apply.

This seems to imply a Captain award could be prior to 400 hours.

F. Probation
1. A pilot will be on probation until the earlier of:
a. 400 hours of block time (inclusive of O.E.),
b. completion of 12 months of aggregate service, or
c. conversion to a Captain position.
