The Berkshire Hathaway annual meeting is this weekend and both Delta and United have extra flights. I've only listed flights one direction each day but what goes in, must come out both days except the Delta 757 from LGA and the Delta A319 from LAX stay on the ground all weekend and don't go in and out twice.
Security lines in OMA on Sunday will be horrible, especially Sunday morning as most of the mainline flight additions are all in the mornings. (I flew out on a Wednesday morning end of February at 6am from OMA and the security line took 65 minutes...can't Imagine what all these extra flights will cause!)
Southwest, Frontier and US Air did not add flights but doing some quick searches, almost all their flights are sold out 100% for these days too.
To note, this will be the first time ever that Delta will have 11 mainline flights in a single day from OMA.

Delta: 9 mainline flights.
ATL-OMA: 1x757*, 2xMD90, 1xCR9, 1xCR7
