It expects to ship about 30 planes this year. Bombardier has held back CSeries sales because airlines are examining how the 100- to 150-seat planes can be used on routes that best accommodate that number of passengers compared to smaller regional jets or larger planes like Boeing 737s or Airbus A320s. Trade dispute with Boeing Bombardier is currently facing a trade dispute with Boeing Co. ( NYSE:BA ). Boeing is accusing Bombardier of selling CSeries planes in the U.S. below cost because of subsidies that violate trade rules. Bombardier has denied the accusations. If Boeing wins this dispute, that could have a material adverse impact on the CSeries program. But there is no effect so far on discussions with potential customers, according to Bombardier's CEO Allain Bellemare. A few days ago, we learned that Delta Air Lines Inc. ( NYSE:DAL ) was coming to Bombardier's defence in the Boeing dispute.
