[QUOTE=kronan;1795217]Relevant section is 8.A.4.b.ii a deadhead is included in a single duty period exceeding 11:30 (lead in verbiage is A class of service higher than coach shall be authorized if: )
The contract section is the only thing that matters here. If you are entitled to FC per the contract then you are allowed to book it. I have used this particular provision on back-end DH's more times than I can count.
While the people in Global travel are nice and certainly work hard for the crew force they do not have supervisory authority over a pilot, in that they cannot tell me what I can and cannot book. I would politely tell them to book the ticket and if there are any issues I would be happy to entertain a call from my fleet manager.
