Narrative:
On out flight from clt; the original weight and balance on the release was for northbound departures in clt; however clt was departing south that day. We elected to increase the thrust setting; and requested new tps (takeoff power setting) data for runway 18C. The new tps indicated 24;000 dry with a flap setting of 1. After taxiing out; we were told by ATC we had a wheels up time of about 25 minutes and were told to hold short of the runway on a parallel taxiway. We still had not received our load closeout; and had to contact operations. After receiving a load closeout; the ZFW (zero fuel weight) had been increased due to over fueling so we requested a new tps; which then indicated a flaps 5 setting. Around the same time; ATC had told us that our departure time had been moved up and to taxi to the runway. We changed the flap setting to 5 in the FMC but forgot to change the flap handle. Once airborne; on the initial climb out; we noticed what had happened. The flight continued without further incident.
