Japan Airlines (JAL) and All Nippon Airways (ANA) are expected to increase fuel surcharges up to double their current rates on international flights starting with June bookings due to the ongoing conflict in Iran. 
Fuel surcharges are extra costs that are added to airfares in order for customers to cover a portion of the fuel costs. 
Given the fluctuating nature of oil prices, the surcharges are collected separately from the rest of the airfare and vary depending on the market price of fuel at the time. 
The amount customers are required to pay for fuel surcharges is determined two months at a time and announced two months in advance by JAL and ANA. 
They are calculated based on the average price that kerosene — fuel that is used to fly planes — had been traded in the Singapore market in the two months leading up to the confirmation of the cost, in addition to the average price of yen in U.S. dollars during the same period.
