Thanks so much for the referral to departedflights.com. I had never seen that before and it brought back and helped me clarify memories. For example, I have a vague recollection of flying PDX-OMA on EA back in the 70's (on my way to ATL) and the stop in OMA had never made sense, but apparently it really happened.
I heartily recommend this site to anybody interested in airline history, and I also thank the creator of the site.
