You can travel with 200ml of perfume, but only if it is packed in your checked baggage. Under the global "3-1-1" liquids rule for carry-on luggage, all liquids, aerosols, and gels must be in containers of 100ml (3.4 oz) or less and fit into a single, quart-sized clear plastic bag. A 200ml bottle exceeds this limit and will be confiscated at the security checkpoint if found in your hand luggage. In your checked suitcase, however, you are generally allowed to carry up to 2 liters of total toiletries (including perfume and cologne), provided no single container exceeds 500ml. To prevent your expensive fragrance from leaking due to cabin pressure changes or breaking during baggage handling, it is highly recommended to keep the bottle in its original box, wrap it in soft clothing, or place it inside a sealed, padded "Ziploc" style bag for an extra layer of protection.
