Atlanta-based United Parcel Service Inc. has assigned larger aircraft on routes to Central and South America, boosting its cargo capacity in the region by 50 percent.

On 19 weekly flights from its hub in Miami, the package delivery and logistics company has replaced the narrow Boeing 757 with the larger B-767, which can carry about 132,200 pounds.

UPS is investing in more of these aircraft to extend its reach in Colombia, Ecuador, Guatemala, Nicaragua, Panama and other countries. Latin American economies grew by an average 6 percent in 2010, according to a news release.

The flights with increased capacity from Miami will serve Bogota, Guatemala City, Panama City, Quito and Guayaquil, Ecuador and Managua, Nicaragua.
