Avianca will lease 14 Airbus A320 NEO planes and two A320 CEO planes to push its daily flights on domestic routes up by almost 25%, from 600 to 750. Neuhaser during a press conference in Colombia's Bogota called the increase of almost 1 million weekly seats "unprecedented growth" in the airline's history. The 16 planes will join Avianca's fleet between October and the end of December, the executive said.
