On 3/2, we pick up tons of new flights we didn't previously do, and they all start the same day. This also accounts for the huge number of weekend 4 days. 3/2 is a Saturday, and many many trips start that day. This is a scheduling quirk that happens 4 times a year when DAL tosses their schedule and reshuffles all the DCI flying.
