Complementary onboard snacks usually include standard airline catering/.sandwiches/cold snacks, wafers/crackers/nuts and beverages(soft drinks, juices and water), For longer trips, you may want to consider optional/special catering which is billed at cost. The caterer arrives an hour before aircraft departure so that prepared catering is fresh. When selecting a menu, remember that small and midsize aircraft generally do not have microwaves, so hot food cannot be reheated before serving. Cold foods are generally a better choice. Keep in mind that aircraft cabins are contained spaces and foods with strong aromas will permeate the cabin.
