Thanks for the advice. I am certainly being persistent. It is VERY annoying to deal with LY's customer service - both via email and over the phone. It is sad that such a great country's airline's customer service is SO subpar. The generic email response did not even address my issue; over the phone I'm told to contact American Airlines. Obviously, we know where that will go. Anyway, AA does not accept mileage credit requests for LY and a few other airlines online. So, I faxed them a copy of each boarding pass. Hopefully that will do something. If not, I'm going to try emailing AA with my issue and/or calling them. I have the feeling they will send me to LY and that LY keeps sending me back to AA. If all else fails, I like the idea of sending a letter to the CEO of LY.
