Taylor Swift’s private jet has taken off on a surprise flight, three days away from her next concert date, with fans guessing it might be on its way to pick up boyfriend Travis Kelce.

The flight plan indicates the plane is on its way to Honolulu where it is due to arrive about 9.20pm (local time) on Tuesday.

The mystery remains as to why the jet is returning to the Hawaiian island ahead of Swift’s next concert in Sydney on Friday.

It is not known who is on board the jet or who it could potentially be picking up in Honolulu.

Swift’s boyfriend, NFL star Travis Kelce, hinted at visiting the superstar Down Under in his podcast “New Heights”, saying he would “venture to an island real soon”.

He also said he would not be appearing on next week’s episode alongside his brother Jason Kelce, leading fans to speculate that he would be in Australia and unable to record the show.

Speaking live with Today on Tuesday morning, Travis’ dad Ed Kelce said he heard the rumours his son was going to travel south to visit Swift on her Australian tour.

“I wouldn’t be surprised if he does,” he told the morning show hosts.

“I actually called him a little while ago and my understanding is he’s on a golf course someplace right now.

“He plays a lot of golf, but it’s mostly in these charity events and I think that’s what he’s wrapped up [with] now.”

Kelce was spotted on Sunday playing virtual golf with friends in Parkville, Missouri – not far from Kansas.

The Cruel Summer singer arrived in Sydney on Monday, after finishing her Melbourne leg of her tour.

She was spotted getting on the plane wearing her boyfriend Travis Kelce’s Chiefs Super Bowl Champions hat, as well as a red top and shorts.

She arrived in Sydney just before 1.30pm, after only a roughly 20-minute delay.

The delay was caused by thunderstorms and lighting strikes in the area.

Multiple other domestic flights were delayed.

Swift’s jet pulled into a hangar in the airport, so that she could leave the plane to privately go to her hotel in the city.

After landing, she joined a convoy of cars where she is believed to have been taken to a penthouse at Crown in Barangaroo.

Jet controversy

Swift recently sold her second private jet, a Dassault Falcon 900, in January ahead of the Australian leg of her Eras Tour.

The pop superstar has been criticised for her frequent private jet use over the past few years.

In November last year, her jet was sent to Kansas City where it picked up Kelce, before taking the NFL star Buenos Aires where she was performing.
