I feel like very little of this comment makes sense? So airlines have debt? What enterprise doesn’t? And their cash flow is provided by customers using credit cards? Again, just like every consumer facing business. What are the airlines supposed to do differently? I can’t figured out your proposed solution, unless it is carbon taxes, which yes, would work quite neatly to price externalities in the airline industry (as well as every other industry).
