First,I made the correction DL has 63% of the O/D traffic,in other words the people of Atlanta,according to a survey in an airline trade magazine,(not Airways or Airlines),the 63% percent of the local Atlanta traffic picked Delta airlines to fly on. Second,I am not talking about operations,sure Delta has roughly 70 or 80 % of the operations,but I was not stating that.
And if anyone wants to see the survey,here is the info. Air Transport World,10/98. By the way,they named Delta, Airline of the year for 98. So when you see in advertisements Delta bragging about being picked,"Airline of the Year",they are referring to this magazine's award.
