For a year and a half long period, United sent a 50-seat jet from Newark to Columbia, South Carolina on Thursday nights, and flew one back on Monday mornings. It seems exceedingly likely that this route existed solely so that former Port Authority chairman David Samson could easily spend his weekends down in the Palmetto State. This sort of graft is hardly surprising when it comes to Samson, who was also deeply mired in Chris Christie’s Fort Lee lane closure scandal.
