Northwest, Continental seek pact with Delta-report=20 =09 Friday August 23, 1:25 AM EDT=20 WASHINGTON, Aug 23 (Reuters) - Delta Air Lines (DAL <http://money.excite.com/jsp/qt/full.jsp?time=3D0&symbol_search_text=3DDA= L> ), Northwest Airlines (NWAC <http://money.excite.com/jsp/qt/full.jsp?time=3D0&symbol_search_text=3DNW= AC> ) and Continental Airlines Inc. (CAL <http://money.excite.com/jsp/qt/full.jsp?time=3D0&symbol_search_text=3DCA= L> ) were expected to announce on Friday that they will seek to form a marketing partnership, USA Today reported it its Friday edition. Continental and Northwest already have a code-share alliance and were reported to be wooing Delta in response to a recent pact between UAL Corp's (UAL <http://money.excite.com/jsp/qt/full.jsp?time=3D0&symbol_search_text=3DUA= L> ) United Airlines and US Airways Group Inc (UAWGQ <http://money.excite.com/jsp/qt/full.jsp?time=3D0&symbol_search_text=3DUA= WGQ > ). Delta, Continental and Northwest would be bound by a 10-year agreement if the deal wins regulatory approval, USA Today said. Officials of the three airlines declined comment on the deal and the potential revenue impact, the newspaper said. The Wall Street Journal reported earlier this month that the carriers are also discussing the possibility of expanding the pact to a broader international partnership, including Air France. Delta and Air France are already linked in Skyteam, a six-carrier international code-share alliance. In a code-share agreement, airlines sell seats on one another's flights, so allowing them to extend their competitive reach without the aircraft and manpower required to expand individually.=20 =A92002 Reuters Limited.=20
