The fact is, both PRS, Upsddown and many others are all correct. On the 'macro' view, Upsddown nailed it. The hiring wave has yet to hit us yet, and if you are hired in the next few years (age dependent of course) your career "should be" epic. Not speaking for anyone else, but maybe tapping into some of the frustration is the 'micro,' or day to day realities of the LAA/LUS merger. I wouldn't tell anyone not to come here, because 95% of the time my biggest frustration is driving to the airport for a turn (Living in base is, IMHO, the easiest way to have a good career)!
There are a million little paper cuts along the way, especially being junior. But as an old friend of mine told me recently - "you don't do this job for the first five years, you do it for the last 20."
