Amazing how an airline can elevate service by just modernizing structures such as the massage chairs in the boarding areas to the massive airbus with the rolls Royce engines with the electrochromatic windows ! And not to mention the flawless service of the aircrew even with the language difference. I’ll definitely fly with starlux again
