Get travel insurance if you have a connecting flight as flight is not punctual. Make sure to pack some basic necessities in cabin bag as your luggage may not arrive. Download some movies for the long flight as selection not great. Bring snacks as unlike other airlines, only meals are provided. Flight otherwise ok for the price - gpod seats and space for economy

If you fly business class Fly on A350 as it has updated interior. Avoid the 777 as it is very dated and is a glorified premium economy by today’s standards
