Travis Kelce‘s trip to Sydney has been cut short — he’s leaving Taylor Swift behind so he can beeline it back to Vegas … where he, Patrick Mahomes and the Chiefs are gonna party!

Sources with direct knowledge tell TMZ … Travis is currently aboard a private flight that’s going from Sydney to Vegas — and it’s gonna be a long journey that sees him landing in Sin City Saturday morning. Quick turnaround, no doubt … he just landed in Sydney Wednesday (US time).

It’s already Saturday there now … so he’ll be going back in time in a bit. In any case, when he arrives in Vegas — we’re told TK is set to reunite with his teammates, including his QB and other players … which our sources say had been the plan all along dating back to the SB.

And if you’re wondering … didn’t they already do that the night they actually won??? The answer to that is yes — but they’re going back again and doing a little déjà vu Vegas-style.

This will actually be the third Vegas trip for Travis in two weeks — he was obviously there for the game itself and the festivities after … but remember, he was also just in Vegas earlier this week on a random Monday, where he played a little golf and chowed down with friends.

In fact, a few eyewitnesses who saw Trav in Vegas that day might’ve actually blown his and the Chiefs’ cover here — a DJ who plays at Toca Madera said he’d been approached about doing a private gig for the guys on Friday evening, but if that’s still going down as mentioned … Trav obviously ain’t gonna be there for that. He’ll be 30,000 feet in the air.
