To ensure your safety, we have temporarily changed our food and beverage offering during flight. For Economy Class, we currently offer individual water bottles, pre-packed snack and antiseptic wipes, while on international flights hot and cold beverages are also served. For Business Class, a “3 course” meal curated by a team of distinguished Chefs, is served along with a wide selection of hot & cold beverages.
I honestly doubt Economy Class catering will ever go back to hot meals though.
