CASTRIES, St. Lucia, CMC - The main opposition United Workers Party (UWP) has expressed concern about the service provided by the regional carrier LIAT. UWP Leader Allen Chastanet says the operations of LIAT are critical to the tourism industry and the overall business market of St Lucia, notwithstanding, the dependency on LIAT for the delivery of professional and efficient service. "Despite the fact that LIAT operates as a monopoly, the airline continues to burden regional governments financially and has consistently fallen short from the required standards which the market demands," said Chastanet , a former Tourism Minister.
