Cathay Pacific Airways is considering launching all-freight services to Dallas and Atlanta this summer. The plans coincide with the delivery of a half-dozen freighter aircraft later this year, following the addition of a new Boeing 747-400 cargo plane last month. Cathay spokeswoman Carolyn Leung said: 'We are interested in operating to more cities in North America, but there are planning and operational issues yet to be sorted out.' If the route were approved it would operate three times a week, Ms Leung said, adding that additional stops could be added. In January, Cathay returned to the Shanghai market with a daily freighter service from Hong Kong after a lengthy battle with Dragonair for mainland route rights. While Cathay awaits more opportunities to expand in the mainland - an air services deal signed between Hong Kong and Beijing last year gives it the right to apply for new passenger services and additional freighter capacity to Shanghai by late next year - senior managers said the airline planned to boost transpacific flights. The airline operates 18 freight-only flights per week to the United States and Canada, as well as passenger and freight flights to Los Angeles, San Francisco, New York, Toronto and Vancouver. Ms Leung said Cathay expected the delivery of nine new aircraft this year, including six Boeing 747-400s that were being converted into cargo planes.
