Jimmy Carter carried out this travel ritual 'every time' he boarded a flight

Jimmy Carter, the 39th President of the United States, died at age 100 on Sunday.

Many Americans are paying tribute to the farmer and former one-term governor of Georgia, highlighting his integrity and devotion to humanity. 

During his presidential bid, Carter could be seen flying in "Peanut One" while campaigning - a nod to his humble days as a peanut farmer.

Delta Air Lines posted a tribute to the late president along with a video on X.

"Every time Jimmy Carter flew Delta, he shook hands with each person on the plane. Because that's who he was. Someone who treated people as people," the post read.

Delta CEO Ed Bastian posted a tribute to President Carter on LinkedIn, highlighting Carter's "life in service to others."

"Their legacy lives on through the incredible work of The Carter Center and in the hearts of all those they've impacted," wrote Bastian.
