The umbrella deal is created to supply aircaft to four airlines in which Franke's Indigo Partners investment company has stakes: US -based Frontier Airlines, Mexico´s Volaris, Chilean carrier JetSmart and Hungary's Wizz.
The company is negotiating to sell 430 A320neo single-aisle planes valued at more than $40 billion to US investor Indigo Partners, people familiar with the matter said.
Indigo controls Frontier and Chilean low-cost start-up JetSmart and also holds stakes in Mexican budget airline Volaris and European low-cost carrier Wizz. Airbus declined to comment. The Dubai-based carrier wants a commitment from Airbus, which hasn't sold any A380s in over two years that ensures the viability of the double-decker for the coming decade and half.
The order, believed to be the biggest ever for Airbus, will more than double the value of the airline's sales for the year.
The deal represents the largest single order for Airbus planes by volume and comprises 273 A320neos and 157 A321neos, worth a combined $49.5 billion at list prices.
The deal is expected to be officially announced later Wednesday at the Dubai Air Show, they added.
In a statement, the Hungarian LCC said that while deliveries will start in 2022, the bulk of this order's aircraft will be delivered in 2025 and 2026, following on from the delivery of the 110 Airbus A321neo aircraft ordered by Wizz Air in 2015. The latter is weighing an order for as many as 175 narrow-body planes that could be split between the A321neo and Boeing's 737 Max. An order of 20 jets would be valued at US$8.7 billion while an order for 36 of the aircraft would be worth $15.7bn at list prices before discount.
