Don't forget that you can do 1st Class if total duty time exceeds 11:30.
8.A.4. Class of Service for Commercial Deadhead Travel
... b. A class of service higher than coach shall be authorized if:
i. a deadhead exceeds 5 scheduled block hours; or
ii. a deadhead is included in a single duty period exceeding 11:30; or
iii. the scheduled block hours of a revenue flight plus the scheduled block hours of a deadhead in a single duty period exceed 8 hours. However, if a domestic duty period does not exceed 11:30 and a deadhead within that duty period does not exceed 1:30 (OAG) block, the deadhead may be scheduled in coach.
Deadhead greater that 5 hours is YOUR deviation scheduled deadhead (had to go thru ATL once to qualify- but worth it).
Most typical duty period exceedance is on the back end when you deadhead out with less than a legal rest period. As an example: arrive 0600 and deadhead before 1400 = less than 8 hours rest means same [effective] duty period. (Domestic is most restrictive)
12.C.6. Domestic Rest Provisions
a. A domestic rest period shall be scheduled for not less than 9 hours (8 hours when the following duty period consists entirely of deadhead to base), and shall operationally be not less than 8 hours.
Good Luck.
