Answer:
The supply of airline flights decreased.
Explanation:
The market price of airline flights has increased. The increase in the price of jet fuel is said to be the reason behind this. An increase in the price of fuel will increase the cost of production for flights.
This increase in cost will cause the supply to decrease. As a result, the supply curve will move to the left.
This leftward shift in the supply curve will consequently cause the price to increase.
