From the July Boeing Newsletter: Reserve Duties: This month we had three incidents where crew reported unfit for duty after being called out from reserve. Crews are reminded that they are required to call Crew Operations and declare that they are unfit for reserve duties before the reserve period commences. Calling unfit after the callout, in one case only 1:14 prior to sign on is not acceptable and can lead to delays and disruption which is not in our customer’s best interests
