Copa Airlines of Panama will receive 13 Boeing 737-800 aircraft and has options for purchasing eight more, the company has announced.

The aircraft will fly on the airlines’ route network across Latin America.

Copa Airlines CEO Pedro Heilbron said that the 737s currently used by the airline have been a major factor in the carrier’s success, offering operation and cost efficiencies and encouraging the growth potential of Latin American aviation.

The 737s ordered by the airlines will feature curved wing ends, which improve fuel efficiency and lift while reducing engine wear and carbon dioxide emissions.
