Qatar Airways began Boston-Doha flights last week using the brand-new Airbus A350. Qatar joins Emirates, Turkish, Cathay Pacific, El Al, Copa, JAL, Hainan Airlines and whichever other names I’m forgetting, all of whom have added long-haul routes out of Boston-Logan in the past few years. The new service is not without controversy, however. A group called the Alliance for Workers Against Repression Everywhere (AWARE) has been running full and half-page ads in the Boston Globe, accusing Qatar Airways of exploiting its workforce — particularly its female employees. Such accusations are not new for the Persian Gulf carrier, and have dogged airlines like Emirates and Etihad as well. Hostile conditions faced by their employees, some argue, is one of the reasons these airlines are able to offer such affordable fares. AWARE lays out its case here.
