Airline Data and Analysis

How things have changed! I took my first flying lesson way back in 1965 at the Lake Elmo, MN airport. If you consider both of my parents worked for Northwest Airlines when I was born in 1950, I've been connected to the airline industry for well over a half century.
To keep it short, after a few years flight instructing, flying charters, some corporate flying and a couple of years as an engineering test pilot; In 1974 I fulfilled my childhood dream and became an airline pilot. I am currently near the end of my flying career and an International wide body Captain for a major airline. About 25 years ago, I became an active trader in equity and option markets. Along the way, I attended Lakewood State JC and the University of Minnesota. In order to learn more about corporate structure and what all of that -stuff- meant in the never ending stacks of corporate financial reports, I took courses in finance and investments. Over the past several years, I have provided numerical analysis and consulting for various labor entities and participated on a few investment/airline message boards using the names Bob H and Numbersbob. I believe my direct involvement in the airline industry combined with the financial knowledge I've acquired provides me a unique insight into the industry beyond number crunching that is not shared by most analysts. If you have any comments or suggestions to make this web site more user friendly, I hope you will forward them to me. Sincerely, Bob Herbst email me at- bobh@airlinefinancials.com |
