I like Josh' answer because I too have served as a Consultant early in my career and it has offered me the opportunity to travel.
Good luck to you!
There are many careers thats travel a lot. I suggest first finding out what industry you want to work in; e.g., technology, food, biotechnology, banking, etc.
Most industries have sales professionals who travel a lot to do sales. Additionally, consultants often have to travel a lot as well. I'd imagine the public relations, corporate development teams travel a lot as well.
As I am in the pharmaceutical.biotechnology industry, one such position for travel is called a clinical research associate. They visit hospitals to make sure the hospitals are conducting clinical trials appropriately.
Hope this helps!
I also like working for companies that are large and with international impacts, because the world becomes your travel landscape. When I worked with an online travel company, I went to 10 new countries that I had not visited before including Australia, the Philippines, Malaysia, Egypt, Germany, England, and the Netherlands. If you speak a second language, any language, you increase your chances of being tagged for travel over those who only speak English.
One way I made it happen for me was to organize and lead special interest tours for photographers, although your groups could have other special interests in common as well. This worked especially well for me as money could be made selling the tours and later licensing photos taken on the tours to publications.
Note, however, that there was virtually no competition when I started my photo tours business four decades ago and the field is quite crowded today. But the lesson is to think outside the box and come up with your own business idea based on a skill you have that would provide a profitable means for you to travel.

For long-term or international travel, the best industries I can think of would be airlines and cruise ships.
