Narrative:

Awaiting takeoff in msp, a thunderstorm passed over the field. Very brief, intermittent hail (pea sized) fell for 15-30 seconds. We departed in sequence after the storm had passed. Arriving in mco, a passenger remarked that we had 'dents' in our wing. An inspection by company maintenance revealed hail damage to the ailerons and flaps. No adverse WX was encountered en route. The hail episode was so brief and minor that we never suspected damage. No information is given to us in ground school about the susceptibility to damage that certain areas of this aircraft are prone to.
