<h3>
What are fixed and variable costs for an airline?</h3>
In contrast to variable costs, which change over time, fixed expenses remain the same. Variable costs, which include things like fuel, oil, maintenance, landing fees, etc., on the other hand, are subject to change. The fixed costs do not change regardless of how much time you spend flying your aircraft.
