Boeing Co. announced an order for 75 of its 737 single-aisle airliners with a list price of about $8 billion from Jet Airways India Ltd., ending a sales drought at the biennial Dubai Air Show.br The order, which was already on Boeing's books with the buyer listed as undisclosed, is comprised entirely of re-engined Max8 variants, Mumbai-based Jet said at a press conference with Boeing at the Gulf expo Monday.br The announcement created some momentum at the Dubai show, which on its first day Sunday saw only a single order for two Boeing 777 freighters from Etihad Airways PJSC.br That contrasts with the $179 billion in combined transactions for the U.S. company and rival Airbus Group SE at the 2013 show.
