I have limited knowledge of the industry but I know of at least four commercial airplane sellers: Bombardier, Embraer, Airbus, and Boeing. Between (at least) those four (and buying used planes), airlines have drastically cut the cost of domestic flights. The state of the airplane market seems to be "okay". I do know that the US government did side with Bombardier (CA) from a Boeing (US) lawsuit: https://www.cnbc.com/2018/01/26/boeing-loses-trade-case-over-bombardier-passenger-jets.html https://www.cnbc.com/2018/01/26/boeing-loses-trade-case-over... So it seems anti-trust is at least a "threat-in-being".
