American Airlines premium class meals prove that upgrading might not necessarily be healthier. A chicken or fish entree plus salad with dressing and rolls or rice contains about 500-600 calories, depending on the use dressing, toppings and butter. Add virtually any desert that the airline offers and calorie count shoots north of 800.
"Special meals," such as vegetarian meals, kosher or halal meals, and gluten free meals often offer a smaller calorie count. Bean-based dishes such as American's bean and pepper medley, with fruit and rice as sides, is a 300 calorie offering. Passengers should keep in mind that vegetarian meals must be ordered in advance. This can be done by calling the airline.
