Expedia Failed to Provide Support After American Airlines Flight Delay

I booked a flight through Expedia under the name Modi with American Airlines. My flight was delayed by about 2 hours. Due to this delay I incurred extra expenses that I would not have had under normal circumstances. I have supporting documents showing these additional costs. Although I booked and travelled according to the information provided by Expedia, I was not informed in a helpful way about compensation or support for the delay and the extra expenses it caused. I expect Expedia to review my reservation and flight details, evaluate the delay and reimburse my documented extra expenses, or clearly explain what solution they can offer.
