Minimum rest for the inbound tech crew concerned, then dispatched accordingly.
This does NOT make the commercial department pleased, but OTOH, not much you can do about it.
Sending pax to the hotel is never cheap...but it happens.
Once had the chief pilot call me in the same scenario, in the middle of my minimum rest and "request" that I operate now (please).
Told him that the minimum rest started from the time of his telephone call, and to not call me again I until was legal.
Was in accordance with the GOM, and he later said...sorry.
Clearly he got the message.
Told him later that the companies insurance cover would have been VOID in the event of an incident with improperly rested crew...and so it would have been.
Anyone disagree?
