CLT is correct! And, with that answer, we close out this quiz. I hope all of you had as much fun answering the questions, as I did putting them together.

EA was much larger at CLT than they were at GSO or RDU in the 1970s.

In Jan, 1976, EA flew nonstop from CLT to CAK, ATL, AGS, BOS, CHS, CHA, ORD, CLE, CAE, CMH, DAB, DTW, GSO, BDL, JAX, MIA, JFK, LGA, EWR, MCO, PHL, PIT, RDU, STL, and DCA. Some of the cities EA served from CLT, like CAK and DTW, were cities they were not authorized to serve from ATL. However, EA's CLT hub also made sense geographically because it was faster to route traffic from other cities in North and South Carolina through CLT, than it would have been to route traffic from these cities via ATL.

From GSO, EA only flew nonstop to ATL, ORD, DTW, MIA, LGA, PIT, ROA, and DCA.

From RDU, EA just flew nonstop to ATL, BAL, CLT, ORD, MIA, LGA, EWR, PHL, RIC, and DCA.
