It looks like the old unable to commute policy is back in there. It allows "off line" backups to count.

A commuting pilot who travels to his base by air will not be eligible for treatment under Section 23 Y. 2. unless he has attempted to travel on at least two flights (on and/or off line) that:
a. show adequate actual seat availability within 24 hours of the departure, considering the pilot's seniority and the normal load factor of the flight; or, on which the pilot has a jumpseat reservation, b. are scheduled to arrive at his base at a reasonable time before his scheduled report, and c. are separated by at least two hours.
