It depends what you are looking for. Freeware or payware? GA airfields or big international airports? Freewarepackages with airports are not very common. You can get the FreeFlow packages at
http://www.fs-freeflow.com/ . They are nice. Most freeware airports however come seperated and are available in the downloadsection. Then you have the payware packages like Georender 1 to 6 by Lago, Flightzone 1 and 2, Misty Fjords, Tongass (all GA airports) and the Fly Tampa series (big international airports). Not cheap but very good.
