Not quite. Atlanta to Bogota and back is NOT a Delta One route - it has only recently been operated with lie-flat equipment, and may receive the Tumi amenity kits, but the meal service will NOT be Delta One - it will be like Delta's other "Business Class" routes to South America.

That and the difference in flight time (plus cities and service level and things to do) make Lima much better than Bogota to me. But, ATL-LIM-ATL is Delta One, and ATL-BOG-ATL is NOT Delta One, but rather only operated with lie-flat equipment (so there are no cheese plates, no make your own ice cream sundaes, and only 1 meal service instead of 2).
