Coming back, I remember I was on United for the ORF-ATL leg and changed over to Eastern. Got on the Eastern flight to continue on to DFW and while we were still boarding the captain came on and said a threatening note had been found against our flight in one of the restrooms in the terminal and we had to get off. That particular Eastern flight had also used airstairs. They took all the baggage off and we all had to identify our luggage and whatever was left over didn't go on our flight.
I think Eastern and Delta both had at least some gates with jetways, but some of the other airlines didn't.
Anyway, here is a postcard from around that time period:
Since I only went through the old terminal those two times and it was so long ago, I really can't remember much else. Sorry.
