Regarding DHD, there is some very contradictory published information out there and I smell a revision, somewhere, in the future.

The company can't tell FAs that DHDs must clean and tell Pilots the opposite. You are either right, or they used the wrong word when they typed Duty in that last sentence. Perhaps they really meant operating pilots.

Maybe this would be a good question for the next episode of Ask Johanna? Is it only operating pilots that are exempt from the expectation to clean, because this is what Inflight is being told and what was published in the field notes, and elsewhere.
