The type of food varies depending upon the airline company and class of travel. Meals may be served as "one tray" or in multiple courses with no tray and with a tablecloth, metal cutlery, and glassware (as in first and business classes). The airline dinner typically includes meat (most commonly chicken or beef), a salad or vegetable, a small roll, and a dessert. Caterers usually produce alternative meals, e.g. kosher, halal and vegetarian. These must usually be ordered in advance, sometimes when buying the ticket. Some airlines do not offer a specific meal for vegetarians; instead, they are given a vegan meal. Some of other special meals include
Cultural diet, such as Chinese, French, Japanese, Indian or Italian style
Infant and baby meals
Medical diet which varies from low/high fibre, low fat/cholesterol, diabetic, peanut free, non-lactose, low salt/sodium, low-purine, low-calorie, low-protein, bland to gluten-free
Religious diet, such as Hindu, Muslim or Buddhist (i.e Asian vegetarian) diet
Children's meals, which often contain foods that picky children will enjoy such as baked beans, mini-hamburgers and hot dogs.
