If you’re looking to travel around the world without a major hotel, you’re going to want to plan a quick itinerary.

If you can afford it, that is.

A new study has found that you could save about $10,000 per year on airfare in most of the world, with the caveat that you’ll have to spend at least 10 days out of the country. 

This study from the Harvard Business School’s Center for International Business and Finance (CBIF) and the American Association of Travel Agents (AAA) suggests that travelers will save between $10 and $30,000 by avoiding the typical hotel deals, such as a 3-night stay at a budget hotel in Kathmandu, Nepal.

The report, titled Airfare: What to Do, and What to Expect, was published on Wednesday and was based on data from airlines that collected data between 2014 and 2016.

The researchers looked at flights between five major cities: Beijing, Shanghai, Seoul, New York and Los Angeles.

They took into account the number of days in each city, the length of the trip, whether the trip would cost more or less than a hotel stay, and whether or not the flight was to a major city.

The airlines in the study averaged their domestic airfares and included a bonus if the flight had a domestic stopover.

While the study only focused on the major cities, it shows that if you’re planning a trip that takes place within the United States, you should look at options outside of the US.

The travel agencies found that an average domestic flight could cost between $6,700 and $11,200.

For international flights, the average cost of the domestic flight was between $8,600 and $10
