One piece of advice that will help you move on, and I mean this in the most helpful tone I can, attention to detail.

How you do ANYTHING is how you do EVERYTHING. This entire post was nearly an illegible mess. If you approached a Delta interview with anything less than 100%, you were dead in the water before you started.

If you want it (AA) get a resume service, get an interview prep, get a nice tailored suit, read at least 2-3 books on their entire history and how they got where they are. Find out what the successful people are doing, and do 10% more than they did. The world is full of underachievers, if you do just 10% more than the average you’d shine. Make yourself so polished that you can’t be ignored. Leave no doubt.
