I hear you saying that your airline job is down the tubes, and you need a job, so you would like to find a corporate job. Apparently because no airlines are hiring now and you want someting to pay the bills until job cycle turns upward again. Not to be harsh, but why is that my problem?
Awhile back when times were better, every once in awhile a regional pilot would ask "How do I get into corporate?" Apparently feeling sick of the grind, and without upgrade prospects at the regional, a nice cushy corporate gig might be more fun. Again why is that my problem?
I used to get resumes from retired airline captains with 20,000 hours who were applying to fly a light corporate jet. I had trouble believing a 65 year old guy like this really is of the mindset to do all the chores required to keep an operation like this going.
In 121 the customer is nothing, zero, a threat on a bad day, an annoyance on a good day. In corporate the customer is not always right, the customer is not even king, the customer is *GOD*.
If you want an aviation department manager to offer you a job, he will have to believe you will make his life easier rather than harder, not embarrass him, and not cost the company a bunch of money.
