On source 4, both the elasticity vlaues are negative. But while solving for elascticty the author has considered price incease for frequesnt flyers and price decrease for exploreres. Also, while calculating for exploreres 990 passenger capacity is considred. I am confused as to why this was taken diffrently.
This is exactly the reason why the price is increased for frequent flyers while decreased for explorers to increase volume and in turn revenue despite both the customer segments have negative price elasticity.
That makes sense, thank you!
