Agriculture and airlines tend to use futures to hedge, not options.

A (long) futures contract is the right AND obligation to purchase a commodity at a set price at a set time (and place).

A (call) options contract is the right BUT NOT the obligation to purchase a commodity at a set price within a set time (for the most typical American-style option).
