Traveling internationally is a big deal for Barker, as he hadn't been on a plane since surviving a deadly plane crash 13 years prior. Ahead of the pair's travels, the Blink-182 drummer posted a photo of the couple kissing while in front of a plane and wrote: "With you, anything is possible." "Anything and everything with you," Kardashian commented beneath the post, adding a black heart emoji. PEOPLE confirmed Kardashian's relationship with the drummer in January. A source later revealed in April that Disick was " struggling" with Kardashian and Barker's romance. "Before Travis, Kourtney's relationships were never serious. It was more like flings. With Travis, it's different," the insider said. "Scott was pretty shocked when he found out that they are dating, and he can tell that they have moved very quickly. His kids love Travis, which is also hard for Scott."
