Why is it that Delta has gone to a method of operating seven different flight schedules for each day of the week? I remember even a few years ago where one schedule was used for nearly every day of the week, if not all week.
Using the online timetable, take the week of March 9-15 for example, CMH-ATL:
Mon- 1 757, 1 73G, 3 M88, 1 E75, 1 CR9
Tues- 1 757, 1 73G, 4 M88
Wed- 1 757, 1 73G, 3 M88, 2 E75
Thurs- 1 757, 2 73G, 3 M88, 1 E75
Fri- 1 757, 1 73G, 4 M88, 1 E75
Sat- 1 757, 2 M88, 2 E75, 1 CRJ
Sun- 1 757, 3 M88, 3 E75
To be more specific, the first flight of the day alternates between an MD-88, 757 & E175, depending what day of the week. One of the later flights (departure time rotating between 2:45, 2:55 & 3:00pm) alternates between an 737-700, MD-88 and E-175. And while the aircraft used each day may look similar, the times differ.
Does this have to do with right-sizing schedules based on capacity, aircraft usage, or something similar? And how well does it work in comparison to having a set schedule with the same flights and equipment seven days a week?

WOW...from a resource max model view that makes allot of sense, but the logistics of pulling off day to day A/C rotation and time slot adjustments sounds like a NIGHTMARE. Do any ops people want to chime in on this?

It's call "day of week scheduling" and what they're doing is matching aircraft and frequency to the market. You'll see the same scheduled from week to week most times but not always. It does create more headaches for the ground crews which have to have the right staffing but it appears to do the trick for matching the right aircraft and frequency.

Well think about it, Tuesday, Wednesday and Saturday are not popular days for business travelers so hence a decline in flights. CO does that here in CLE and has for years. So this is not something that DL thought up.

I noticed a similar thing in DL's sked between CLT and ATL. I believe there's a flight around 330p that on one day is a 737-700, another day it's a 737-800, and then an MD-88 the other 5. A similar pattern of different a/c types also exists on the morning CLT-ATL flights.

After Delta filed for bankruptcy, they hired Continental's head of route planning, if I recall. CO has used this for years, and it is why they generate superior yields. Anyway it is an unheralded reason why DL's finances have improved post-bankruptcy.
