Narrative:
In cruise; advised by passenger in coach of a 'fluid' coming back from right wing. Had flight attendant assess. Confirmed. To get a more 'specific' determination of location; etc; had deadheading captain on board assess visually. Confirmed; leak from flap fairing. Assessed all cockpit psi and quant parameters -- all normal so far. Contacted maintenance control to discuss. Through their history search; etc -- leak via its location and color and absence of any parameters of loss of fluids (hydraulic/engine oil; etc) we determined safest course was to continue on. Maintenance control said most likely a loss of fluid from 'flap transmission oil.' after consulting several times with dispatch and maintenance control en route to confirm; and suitability to continue; we did. Conservative actions taken -- advisory to flight attendants. Had equipment standing by at destination. Slowed aircraft up early to deploy flaps (early during approach) to verify in due time appropriate flap operation. All operations were normal.
