On Sept. 26, 2002, Maher Arar, a Canadian citizen born in Syria, was returning to Montreal from Tunisia when he was taken into custody at New York's Kennedy Airport.

This phrase is a play on driving while black (or DWB), having a car pulled over (by a police officer) for no other reason than the driver is black. This in turn was a riff on driving while intoxicated (DWI), an actual offense. Some phrases similar to flying while Muslim are flying while Arab (1999) and flying while brown (2001).
