This is a great tip I read recently on a Forum.
Think back to the last plane trip you had or listen out for it when you take your next one.
When the pilot comes on over the PA system to welcome you aboard and provide details of the flight. What do they sound like?
Nervous, hesitant, confused, ill prepared?
No! They exude Confidence, Calmness & Control.
Do that as an MC and you are halfway there.
