Yep, as much as I like and respect Boeing and thier legacy, they pulled a punk move and tried to stonewall Bombardier's export of the C series in the US. For decades, airlines have asked for a narow body aircraft to fill the 100 seat market since Boeing snatched up the MD 95, rebranded it the 717 and discontinued it. Instead, they tried to pump up thier highly successful 737, and told the airlines what they needed instead of listening to them and designing a clean sheet new airframe to fill that 100 seat niche market. Along comes Bombairdier with the C series which is exactly what the industry had been asking for. Delta orders a huge number of them. Boeing gets nervous as they see it's huge threat potential to thier future sales and market share. So Boeing petitions the government to leavy heavy tariffs on imported airliners. (Which is ironic and hypocritical since Boeing exports most of thier products, especially to ME3 and NAI, whom hurt American airline business). This obviously screwed and ****ed off Delta and Bombardier. Airbus is grandfathered out of having to pay the new tariffs (who Delta has a large deal with) stepped up to the plate and saved the day. They made a deal with Bombairdier to import the C Series under the Airbus certificate. Boeing's plan backfired. As part of the deal, Delta cancelled thier 787 orders in exchange for A350 orders, causing those 787 orders to dump onto the market. Thus AA picked up those options for cheap and cancelled thier A350 orders, if I understand correctly.
