The phrase "avoid fuel surcharges" refers to taking steps or actions in order not to have to pay additional fees for airline tickets due to fluctuations in fuel prices. Fuel surcharges are added on to the cost of an airplane ticket when there is a significant increase in the price of jet fuel, which can cause the overall cost of the flight to rise as well. In order to avoid these additional fees, travelers may choose to book their flights further in advance or be more flexible with their travel dates and destinations, as some airlines offer discounts for non-peak times or less popular routes. Additionally, it can also help to compare prices from multiple airlines and use strategies such as buying a round trip ticket instead of two one way tickets in order to save on additional fees.
