Dr, do a few of these, and you will soon find the difference between "booking" and "ticketing". An (ill trained) agent can book you on whatever you want. You want to book JAL to Tokyo? Fine. You want to do 18 transcons? Have a blast. But the "final" say will be from tariffs, who has the decision of denying the itinerary or of charging you a bucket of bucks to do it. Though, I suppose the actual "final" say is up to you and whether you want to pay for it...
