Since the Iran war broke out, the Strait of Hormuz has effectively been blocked. The Strait is one of the world's busiest oil shipping routes - leading to fears about shortages of jet fuel. Prices for aviation fuel more than doubled after the war began, and the cost of some plane tickets has gone up dramatically. In May 13,000 flights were cut from schedules. And European travel operator Tui says its customers are appearing more cautious about booking summer holidays due to the Iran war.

Loads of people have questions about jet fuel shortages, airlines cancelling flights, and if jet fuel could run out. This has also sparked a conversation about sustainability, with people asking if reducing flights could have a positive impact on the climate, as well as whether eco-fuel could replace jet fuel. In this episode we sit down with BBC business reporter Emer Moreau to answer all your burning questions about jet fuel shortages.
