Five agents worked on it diligently, and got it to work and then not work and then work, etc, until they sent the flight without us.

They could not have been nicer, but we were denied boarding involuntarily and were delayed in our arrival by 24 hours.

All of the online sites that I read -- including the USDOT and AA websites -- describe Denied Boarding Compensation in the context of oversold flights. This was not an oversell -- but it was 100% AA's fault, and their faulty system caused our delay and our inconvenience.

What are the rules here? Can I ask for compensation? Will I get it? How much is it for? How do I do it? Anyone have experience with this?

Thank you!
