If firmed, this will make Indigo Partners one of the largest customers for the A320neo aircraft family, rivaling the 404-aircraft backlog of AirAsia and the 430-order total of Indian low-priced carrier IndiGo, which has no business relationship with the U.S. investment firm.
The deal more than doubles Airbus' order book for the year.
"An order for 430 aircraft is remarkable, but it's particularly gratifying to all of us at Airbus when it comes from a group of airline professionals who know our products as well as the folks at Indigo Partners do".
The planes aren't all for one airline.
Airline pioneer Bill Franke placed a historic order for 430 Airbus A320neo-family jets on Wednesday, doubling down on investments in ultra-low cost airlines that offer bargain ticket prices coupled with a slate of extra fees. "We are hopeful it will become a firm order in the coming weeks", said long-time Airbus sales chief John Leahy who is set to retire from the company.
The deal includes aircraft for Wizz Air, Frontier Airlines, Jetsmart and Mexico's Volaris.
Wizz Air (W6, Budapest) has announced it has signed a Memorandum of Understanding (MOU) with Airbus (AIB, Toulouse Blagnac) for the purchase of a further 146 Airbus A320neo Family aircraft entailing seventy-two A320neo and seventy-four A321neo. Indian low-priced airline IndiGo (which isn't connected to Indigo Partners) bought 250 Airbus jets in 2015. It agreed buy 150 Boeing 777X planes and 50 A380s, which were worth a total of $99 billion at list prices.
