Airbus said it had reached a deal worth roughly $50 billion at list prices -- to Indigo Partners, which owns several low-cost airlines around the world. Fabrice Bregier said that this was the biggest deal in Airbus's aviation history. Only a few hours later, Flydubai signed the draft agreement at the Dubai Airshow for over 737 MAX jets, according to a Boeing statement. The provisional deal is worth $27 billion. Boeing said it was the biggest ever order from the Middle East for single-aisle passenger planes.
