This is mainly to any Delta pilots who fly the CLT to ATL route. I've noticed on my many trips through ATL that we seem to follow one of two main routings.
KCLT HOR1.HARAY SPA.MACEY2 KATL - which brings you into ATL from the north to land on rwy 8L/26R
KCLT PAN6.ANDYS IRQ SINCA.SINCA3 KATL - which brings you into ATL from the south to land on rwy 9R/27L
Is there usually a deciding factor for which route will be used. Is there some rhyme or reason? For example, if a flight was be arriving at a gate on the North side of the terminal would it use the north approach into ATL and for arriving at a gate on the South side of the terminal would it use the south approach into ATL?
There is usually a small time difference as well, the southern route is just a bit longer. I've always wondered about this but never got around to asking.

For many city pairs that have high frequency, there are preferred routes published by the FAA. You can check out the back of an Airport Facility Directory (AFD) for these routes. Typically, these routes will be used during busier times which could explain your routings.
These could also be affected by weather. If the winds are favoring a specific runway, it may be to their advantage to route you in a different direction for sequencing. There may be storms off to the north and it may be better to come from the south, etc.
is the CLTATLPR preferred route. There are two others listed there, north and south CDR ("Coded Departure Routes," used for severe weather avoidance, formerly known as "SWAP"), but neither is the southerly route you quoted. The one you quoted is a little longer than CLTATLPR, but quite a bit shorter than CLTATL1S.
Hope that helps a little bit... sorry I don't have any info on the other route.

Just expanding on points already made. While Macey is the preferred STAR for that route, it is also the most heavily travelled STAR in the United States. At certain times during the day, ATL TMU will put out an advisory asking for flights to be dispatched from the northeast via IRQ.SINCA3. Often, we will dispatch flights from RDU, PHF, IAD, etc. via the SINCA STAR. Generally, we will also make a note in the remarks section of the release that says something similar to: "REQUEST LIB.ODF.MACEY2 ONCE AIRBORNE".
