The most common types of round the world tickets are probably the ones that are offered by groups of airlines or airline alliances such as Oneworld and SkyTeam.
These types of tickets are priced based on the stops you make and route you take (route-based tickets) or on the total number of miles you travel (mileage-based tickets).
But sometimes they're a bit of a confusing mish-mash of both. So here's the basic lowdown.
That depends on what you're looking for, really.
Route-based round the world tickets are generally cheaper than mileage-based tickets but they're more restrictive.
They usually don't let you backtrack along the way or fly through the same airport twice. A real problem if you plan to do side trips by air from a hub.
With route-based tickets you also can't have any open jaws — where you fly into one airport but out of another. So you wouldn't want to have your heart set on the Trans-Siberian!
Mileage-based round the world tickets are generally more flexible but also more expensive.
They usually let you backtrack a bit and transit through (stop for up to 24 hours) the same airport more than once. Oddly enough, they also tend to have more route options than route-based tickets!
They give you a decent mileage limit of anywhere from 26,000 to 39,000 miles (about 41,800 to 63,700 km), but of course the more miles you use the more you pay.
Mileage-based tickets do allow open jaw flights. But don't get caught out! Even those surface miles count towards your total mileage flown.
Airline alliances not looking like they're going to cut it? Can't see yourself getting your round the world tickets with just single or partner airlines either?
Not a problem. There's another option.
Actually, it could turn out to be even cheaper and it's definitely a lot more customisable than any of the RTW tickets you'd get with a group of airlines.
