Thanks a bunch!
Those helped me quite a bit, my nerves were hiked up there for a while. An HR friend and a few airline buddies told me roughly the same thing, i.e. not to worry about it. I never felt the need to be "less-than-honest," though I can't say I find minimizing what happened as being so. I didn't attach the court information, but did provide it in the field that requested details of the pretrial diverson program. My license was suspended, so I provided that, too. I don't know what else to do; my HR buddy told me that if it was really a significant issue to the job, they'd [probably] call me to chat about it before I started.
I'll post back in a while, after things are settled, with more detail of how things pan out. Thanks again!
Oh BTW, in this state, yeah; you're criminally liable as an adult, but the offense (being alcohol-related) is somewhat lessened in severity since I was a "minor" in that sense.
