A little grass airfield in the Land of the Long White Cloud (NZMA) regularly does over 1000 a day (but only during a two week period each January).
Busiest day there has been over 1200: -
one controller operating from a portable control tower,
on one frequency,
a circuit full of ab-initio pilots (including a few first solos),
and not forgetting the resident gliders
Checkout Walsh Memorial Scout Flying School for details of the operation.
