Will she make it?

Taylor Swift's last song will still be ringing in the ears of thousands of fans at the Tokyo Dome on Saturday night when the singer is expected to rush to a private jet at Haneda airport that will take her on a time-zone-spanning journey to see her boyfriend, NFL star Travis Kelce, play in the Super Bowl in Las Vegas.

The prospect of this race against time, complete with police escort, crossing nine time zones and the international date line, has fired imaginations, and speculation, for weeks.

At Saturday night's concert, there was plenty of evidence of the unique cultural phenomenon that is the Swift-Kelce relationship, a nexus of professional football and the huge star power of Swift. In addition to sequined dresses celebrating Swift in the packed Tokyo Dome, there were Travis Kelce jerseys and hats and other gear celebrating his team, the Kansas City Chiefs. Some in Tokyo spent thousands of dollars to attend the pop superstar's concerts this week.

To call the worldwide scrutiny of Swift's travels intense is an understatement.

Fans have tracked her jet. The planet-warming carbon emissions of her globe-trotting travels have been criticized. Officials have weighed in on her ability to park her jet in Las Vegas airports.

Even Japanese diplomats have gotten into the act. The Japanese Embassy in Washington posted on social media that she could make the Super Bowl in time, including in their statement three Swift song titles – "Speak Now," "Fearless," and "Red."

"If she departs Tokyo in the evening after her concert, she should comfortably arrive in Las Vegas before the Super Bowl begins," it said.

Swift has been crisscrossing the globe this week already.

Before coming to Asia, she attended the Grammys in Los Angeles, winning her 14th Grammy and a record-breaking fourth Album of the Year award for "Midnights." The show was watched by nearly 17 million people. She also made a surprise announcement that her next album is ready to drop in April.

Then the four concerts in Tokyo, and now apparently a rushed trip to try to make it to Las Vegas to watch Kelce, the tight end for the Kansas City Chiefs, play in the Super Bowl. She has followed Kelce for much of the Chiefs' season.

If it all goes as planned she's then expected to fly to Australia later this week to continue her tour.

"This week is truly the best kind of chaos," Swift posted Wednesday on Instagram.
