At my hometown airport back home in Connecticut (BDL) we get on ocassion a AN-124 which is the largest. I have seen it 4-5 times this year, mostly transporting engine parts for P & W. As for sheduled planes now, Delta brings in their 763ER, 763, and 762 for daily service into ATL, and CVG. Cargo, a couple times a week, Atlas will bring in a 742 and UPS brings in many 763's daily, along with Fedex A310's an ocasional (maybe 2-3 a year) MD-11. Also, omini air cargo and world airways bring in DC-10's along with a couple other cargo carriers who bring in A300's. Quite a few cargos also bring in DC-8's. American, Delta, United, and US Airways all have shceduled 757 service and US Airways will ocassional subsitute a 767, along with United. BDL gets many diversions from JFK, BOS, and EWR so during a storm it wouldnt be uncommon to see 10-15 744's A340's and 777's parked there.
