Businessman was a passenger on the Singapore-New York flight in the Season 3 episode Airborne. He was portrayed by actor Ben Carroll.
House was canvassing the passengers for pharmaceuticals when he came upon a businesswoman. House noted that she had herpes and asked for her Acyclovir. She denied having either, but Businessman sheepishly handed over his Acyclovir. Businesswoman shot him a look and House reminded the passengers that they were in desperate need of medication to treat the sick passengers.
