Boeing landed the biggest order so far of the Paris Air Show with a deal Tuesday for 100 of its 737s single-aisle jets that Boeing's Chief Executive Officer calls "the heart of the market" in the years to come, AP reported. Boeing and European rival Airbus are racking up sales at the air show in the Le Bourget airfield outside Paris, with particularly tense competition between the 737MAX series of planes and Airbus' 320 family of jets. Dutch-based leasing company AerCap ordered 100 737MAX-8 planes after long negotiations, Boeing said Tuesday. The deal is worth up to $10.7 billion, though customers routinely negotiate discounts off list prices. Airbus showcased several deals Monday, and on Tuesday announced that Japanese low-cost carrier Peach Aviation signed a firm order for three A320 jets.
