Everyone uses some form of advantage to get where they go and I don't blame them for that. Unless you were born in a brothel to a crack addict mom and a absent or abusive father, you were born in some privilege. Hell, even just being born in the USA gave you an advantage. If you interview with an airline, the job is yours to lose. Airlines do not bring you in unless you are qualified for the job. If you fail in the process somewhere, you need to look in the mirror.
I failed at too many airlines I care to mention before getting on with Alaska. I still don't know what they saw in me.

Anyway, every failed interview gave me experience to build on and eventually I fooled them.

But seriously, some guys are so, "head and shoulders" over the rest, they get their first choice of airlines. Most of us have to do the best we can with the hand we're dealt. I had no "in" with Alaska. If I can do it anyone can.
Skyhigh you need get over the fact that it did not work out last time at Alaska. Although you have landed on your feet, it is obvious you still have the bug. Alaska hiring again in record numbers. It is never too late to try again. Something needs to change however. I'm sure you would take the job if offered. So make it happen! Or get over it and stop trying to find a reason other than something about you for the reason you failed at Alaska.
