Before arranging a Balloon Exchange make sure you confirm that you do, in fact, have a Balloon: click here.
From there, you search for an Exchange in the same way you traditionally do. Search for the location you’d like to go, when you find a home that interests select “Get in Touch” and check the “Balloon Exchange” option. Arrange the Exchange as you would with a traditional exchange. As with all Exchanges, Balloon Exchanges must be registered through the site prior to the Exchange taking place.
