I hate to say that if you can not tell the difference between a Jungle Jet(ERJ) and a CRJ then you have no business spotting. And you say it was at DSM. I was about to put my foot in my mouth and say we did not fly to DSM but i just remembered we did. Anyways Blueridge is our callsign for both UA and DL. Our old callsign for DL used to be Patriot but then we merged the operating certificates.
I Don't know where I am anymore
