After going through a ringer of horror with three different airlines on Friday, Sebastien and his family retreated home to try again the next day. On Saturday, he and his brood were “selectees” earmarked for special detention by TSA at the security checkpoint. Later, he noticed his ticket had “SSSS” printed in the lower right-hand corner. His return ticket, where he had no special inspeciton, had no such S’s.
