In brief: A lot

There are guidelines for total radiation exposure associated with commercial flights.
A typical airplane flight will expose a person to roughly 1 millirem per hour of radiation. Guidelines from the international commission on radiological protection (icrp) recommend less than 2, 000 millirems per year of exposure. That would mean 2, 000 hours of flying per year before concern would arise.
