Well, not asking for much, I see.

For a 3 hour delay, you are asking for...

2 FC tickets worth approximately 240k miles of ~$15k.

2 yeas of comp status to PLT, which I've never even heard of as a compensation since AAdvantage is run as a separate unit.

All because you decided to leave the boarding area voluntarily to make a phone call outside security.

You are indeed fortunate TWA offered you anything at all. If I were the CSR rep who saw your "request for compensation", I'd laugh my head off and forward the info to colleagues for a good laugh.
