The United States has dropped restrictions on Mexican airlines, reopening the way for Mexico's carriers to apply for new US routes from Mexico City, according to Simple Flying.

The move comes a year after the US blocked 13 Mexico City routes, the report said.

Mexico's airlines can apply for new US routes from Mexico City again, but under continued DOT oversight, according to the report.

The available information covers the lifting of the restrictions and the reopening of the route application channel; further operational details were not disclosed.
