Heights aren't the only obstacle that Kourtney has helped Travis conquer, in August 2021, the drummer went aboard a private jet and flew to Cabo with the Poosh mogul for the first time in 13 years.
Barker hadn't flown since surviving a deadly plane crash in 2008 that killed four passengers, including Travis' security guard and his assistant. He was left critically injured with third degree burns covering 65% of his body and spent four months in burn centers. He said the tragedy took such a toll on his mental health at the time, he contemplated ending his life, per CNN.
