Let's consider the market for airline travel to Hawaii. Currently, the market is in equilibrium, but two events are happening simultaneously that may change the equilibrium. First (as you may have seen in the news), there is a lot of volcanic activity in the area. Effects from these volcanoes can be very severe (including fires and earthquakes) to very mild (smoke in the air). Second, some major airlines have decided to offer fewer perks while flying (charging more fees to check luggage for example). Explain how each event could affect the supply or demand curve, and explain which direction price and quantity change.
