A devoted father didn't let his flight attendant daughter's work schedule keep them apart over the holidays, joining her for Christmas at 30,000 feet.

Hal Vaughan took six flights in three days so he wouldn't miss a second with his daughter Pierce, a Delta Air Lines flight attendant.

"You do your best to keep them thinking you're the greatest dad in the world for as long as you can," Vaughan told Inside Edition. 

The journey began on Dec. 23 as he flew from New Orleans to Detroit, down to Fort Myers, Florida, and back to Detroit. The next day, he joined her on a trip from Detroit to Hartford, Connecticut. And then the day after Christmas, they flew from Hartford to Atlanta and finally back to New Orleans. 

Vaughan flew standby on all the flights and miraculously made it aboard every single time, even getting bumped up to first class on one.

The story gained worldwide attention when a passenger who sat next to Vaughan on one of the flights posted about his story on social media. 

"I had the pleasure of sitting next to Hal on my flight back home," Mike Levy wrote on Facebook Monday. "... What a fantastic father! Wish you both a very Merry Christmas!"

The post has been shared more than 39,000 times. 

"I don't think we could ever top this Christmas," Vaughan said.
