Whether you find that info or not, you'll likely learn that historical data in this business is basically useless. Sometimes you're in the right place and sometimes you're not. You could try and chase and predict the hot category based on historical data. But all history has taught us is that today's gold is tomorrow's trash based on the whims of network planning.

Just some food for thought: If you're relatively junior (which I suspect you are), then it is unlikely you'll ever be as senior in the 7ER as you could be in the 220/320/73N. That is just by virtue of the fact that one is stagnant/shrinking and the others are growing. And seniority is really what determines opportunity. For good trips/days off/vacation/green slips, everything.
