Assuming you have no AA status, Eagle flights with one class have the same onboard service for all passengers. Also assuming you have no oneworld or AS status, and assuming you redeemed for a Saver award (as opposed to an Anytime award) you won't be be boarded early either. That said, you should have access to a lounge at your Eagle flight's departure airport, assuming one exists and your itinerary qualifies for lounge access. Knowing more about your specific itinerary and elite status would help us clarify exactly what to expect.
