I usually tell people there is no way to give advice on what carrier to choose, because there are too many variables to take into account, over the length of a career, so even attrition is no predictor of the quality of a craeer.

That being said, if your personal calculations tell you it's smartest to go to UsAmerican, but you're spending more than about a minute dwelling on first year pay, then there is something seriously flawed with your logic.

Or you're over 60.
