The only real trouble was my connecting flight to Chiang Mai on Hong Kong express which i booked through Cathay Pacific was canceled and I was never informed about this. I was rescheduled on the flight 10 several hours afterwards. Super astonished with the complete experience. Business class is unbelievable. https://hotbizdirectory.com/listings13425860/business-class-flights-to-sydney-from-london-no-further-a-mystery
