From what I understand; Simmons, Metro, Chaparral, BizEx, Nashville Eagle, Executive Airlines (although Executive operated on a seperate certificate, up to last year, but payed by AE and under the same MEC) and a few others where all merged together several year ago, or more, to form American Eagle Airline. One company that is now referred to as L-EGL (Legacy Eagle), since now, the "American Eagle" name has been re-purposed as a 'brand' which is now also operated by other outside carriers. And yes, RAH uses the "American Eagle" name on their PA's, and refers to themselves as "American Eagle". (Disclaimer: I'm not saying that they do this on purpose, but that that's the way their pre-recorded PA's and briefing cards address them when operating an AE flight). We use L-EGL to differentiate ourselves from the outside operators when talking about company issues, and to alleviate confusion as to who we are talking about.
