RCA NashvilleChris Young and Cassadee Pope’s hit duet is now a member of the mile-high club. Monday, the two performed “Think of You” high above Music City on the maiden voyage of the new Southwest Airlines plane known as the Tennessee One. The red-white-and-blue aircraft is painted to resemble the Volunteer State’s flag, in commemoration of three decades of Southwest service in Nashville.

Right now, the two are also busy staging their top-20 hit on tour together, as Cassadee continues as Chris’s special guest on his I’m Comin’ Over trek. This week, they swing through the Northeast, with a stop in New York City Thursday night, before heading to Baltimore, Maryland, and Utica, New York on Friday and Saturday.
