I don't see anyone here misunderstanding any of that. But if passengers refuse to fly Boeing, that changes the numbers quite drastically. And empty fleet is not making money. Switching is expensive, but so is not flying at all, or being forced to fly at reduced rates. If flying with airlines using Airbus is more popular than flying with airlines using Boeing, Airbus airlines will be more profitable, and Boeing airlines will buy less planes. They won't be buying any planes if they go bankrupt.

"Passenger demand doesn't matter" is simply not true. Its effect is indirect, slowed, insulated, but it's still there. At least if sellers like Kayak enable differentiation by plane type.
