MEXICO CITY (Reuters) -Mexico's government plans to cap flights at the Mexico City International Airport (AICM) to 43 an hour, according to an internal government document order seen by Reuters on Wednesday. The resolution, sent by the Transportation Ministry to the airport, is expected to be published in Mexico's official gazette soon, a source familiar with the matter said. The cuts follow previous flight caps at the airport last year, as the government attempts to reduce saturation in the Mexican capital's airspace.
