There are 2 main approaches when it comes to buy a World-Tour Tickets. Note that it works also for multi-destination flights.
Directly with one of the big flight alliances
However the main inconvenience is that you may be limited in the choice of available destinations. Therefore this option could especially suit you if you are targeting main hubs but I would not recommend it for customised or complex routes.
If you want to look into it, the main ones are:
- Star Alliance: with almost 1000 destinations, the prices are calculated according to the number of miles from 26 000 (express world tour, 5 stopovers maximum) to 39 000 (more than 15 stopovers allowed)
- One World: you can choose from the traditional “Global Explorer” option which calculates the tariff according to the number of miles or the “One World Explorer” with unlimited flights on 3 to 6 continents visited and a minimum of 16 flights.
- SkyTeam: it covers around 900 destinations in about 170 countries and allows between 3 to 15 stopovers.
Via a specialized agency
Here are some agencies you can consult online:
- From the US: Airtreks, Tickets round the world, STA Travel (especially for students who have access to even lower prices!), TCS World Travel (luxury travel all inclusive…)
- From the UK: Travel Nation, Round the World Flights, Round the World Experts
- From France/ Belgium: Connaisseurs du Voyage, Zip World, Travel Nation
