Recently, my alarm went off at 3:30am for about a 5am show at the airport. I like to think of myself as a morning person, but that's pretty darn early.
I'll be honest, initial airline training was probably one of the hardest things I've ever done to date. It was a nonstop firehose of information and the pace was quick.
As an airline pilot by trade I've been able to interact with a variety of different people and experience a lot of different places. Along the way I've picked up a plethora of information.
