A round-the-world ticket (also known as round-the-world fare or RTW ticket in short) is a product that enables travellers to fly around the world for a relatively low price. RTW tickets have existed for some time and in the past were generally offered through marketing agreements between airlines on several continents. Now, they are almost universally offered by airline alliances such as SkyTeam, Star Alliance and Oneworld, or else by specialist travel agencies that will spend time helping customize a trip to the consumer's needs. Prices vary but are generally in the range of 3000–5000 USD for an economy class ticket.. Sometimes, depending on airline and stops, it can be as low as 1171 GBP  (~ 1829.57 USD). An alternative for a round-the-world ticket is a continent pass.
