Who is the actor who plays Max?

Max, the guy sitting next to Liz (Bissett) on the airplane back to New York, who lies about the death of his wife, has sex with Liz in the airplane lavatory - who was the actor? He goes uncredited on the cast list. The actress who plays his wife is credited and her screen time was far less than Max's. Who was he, and is there any idea why he's uncredited?
