Private equity firm Indigo Partners has finalised an order for 430 Airbus A320neo family aircraft, which will be operated by four low-cost carriers affiliated with Indigo.
The order, first announced at the Dubai air show in November, comprises 274 A320neos and 156 A321neos. The deal is worth $49.5 billion at list prices.
Indigo has not selected engines for the aircraft.
The 430 aircraft will be delivered to Hungary's Wizz Air (72 A320neos and 74 A321neos), Denver-based Frontier Airlines (100 A320neos and 34 A321neos), Chile's JetSMART (56 A320neos and 14 A321neos), and Mexico's Volaris (46 A320neos and 34 A321neos).
