Latin America's biggest airline LATAM said Monday it will suspend its flights to crisis-hit Venezuela for an indefinite period, following a similar move by German carrier Lufthansa. Chile-based LATAM Airlines group and its Peruvian and Brazilian subsidiaries decided to cut the flights "due to the complex macroeconomic situation that the region is currently going through," it said in a statement. It said challenging economic conditions in Latin America were prompting changes to its domestic and international routes.
