Well, I received my first denial claim today. Not bad in my opinion considering responses were received within 10 days rather than the 30-45 days being promised by Service.com

AA denied the claim indicating that it was weather related. No problem... The other three claims filed were also due to weather compounded with mechanical issues. I guess the end result is how AA resolves the issue on their end as the finality of things. No biggie... compensation mileage have posted to my account and I'm moving on with the comfort of service.com monitoring all future flights for the next year.
