European plane maker Airbus said it finalized a mega order for 430 aircraft with US private equity fund Indigo Partners.
The order includes 274 A320neos and 156 A321neos for Indigo Partners' four portfolio airlines, namely Frontier Airlines in the United States, JetSMART in Chile, Mexico's Volaris, and Wizz Air in Hungary, Airbus said in a statement.
The signed purchase agreement, worth 50 billion US dollars, follows a memorandum of understanding announced at the Dubai Air Show in November.
"The A320neo Family offers the lowest operating costs, longest range and most spacious cabin in the single-aisle aircraft market, making the Neo a great choice for these low-cost airlines in the Americas and Europe," said John Leahy, Airbus' chief operating officer - customers.
Bill Franke, managing partner of Indigo Partners, said "these customer-friendly and efficient A320neo family aircraft form a great platform for continued growth for our family of ultra-low-cost airlines."
