"We will miss you!" Travolta signed off to his 5.3 million Instagram followers.
The 70-year-old played the co-leading role of Danny Zuko in the musical classic opposite Olivia Newton-John, who played Sandy Olsson.
Buckner's Patty was involved in several musical numbers alongside the two, portraying the role of school cheerleader and pal to Sandy.
However, post-Grease, Buckner decided to take a step back from the acting world to focus her attention on raising a family.
