Purchase Gaither homecoming tour tickets on the official Gaither music website, as of November 2015. A listing of events appear when you click on the Tour/Tickets tab at the top of the homepage.
Click on the More Info & Dates link underneath the name of the event you want to attend. Then, click on the Purchase Tickets button for the specific date and location of your choice. This takes you to the website of a third-party ticket vendor where you can purchase tickets. As you are going directly through the band's website, this is one of the safest ways to purchase official Gaither event tickets.
