Maverick M11 is right, while some of us here have fond memories of Eastern (I know that I do, my first flight as a 3 year old was from JFK
on a DC8); at this point in time, most of the flying public does not really remember Eastern, and those that do remember, have harsh memories. Eastern was a great airline, but it had its labor problems, and was already having a difficult financial time when Lorenzo came in and then things only got worse. Most people only remember Eastern as that bankrupt airline (such a shame) and they are basically correct, EA
went bankrupt twice and finally liquidated.
AirTran certainly has little to gain by changing its name to Eastern. AirTran, by some miracle, pulled off one name change, and I do not think that they will try their luck again.
I live in Europe, and many people do confuse AirTran, AmTransAir, Amtrak and the AirTrain @ EWR
