Been down this rabbit hole too many times. If you are already up, awake, ready (process ongoing, but you see the path) and planning on your original airport show…..
And there has been no change prior to this “hop in the shower” (essentially- once you are up to go, you are up for your show).
Now you are awake and ready to roll. You may get crew notifications, CNO alerts, reroutes, etc. MAKE SURE your report time is correct. Scheduling may post a 5 hour delay on the flight, with a 4-5 hour later airport report. You need to call and state NO if already in motion for original report. Scheduling may tell you that you are wrong, speak with a duty pilot at that point. Ask for a supervisor if the transfer isn’t offered. If told NO, there is no need to be nasty (you literally just got delayed HOURS). Call the duty pilot. The situation likely makes complete sense to those not just focused on a pilot in a spot and will get worked out reasonably.
The word NO is something toddlers struggle to understand. For some reason we teach this word to the little minions. yet never want to hear it used. What did we learn?!
NO!
