Taylor Swift has become a staple of Kansas City Chiefs games this season, supporting her boyfriend Travis Kelce. But as Kelce heads toward the season’s biggest game, it’s unclear whether Swift will be in attendance, because she plays a concert the night before—halfway across the world.

The superstar resumes her Eras Tour on Wednesday at the Tokyo Dome, playing a four-night stint in Japan. Just as she scheduled shows on the U.S. leg of the tour, Swift has several days of downtime before her next set the following weekend in Melbourne, Australia.

If Swift were to hop on a plane immediately following her final show in Japan, she would arrive around dinnertime on Saturday night in Las Vegas. The math: Las Vegas is 17 hours behind Tokyo, and the flight takes upwards of 12 hours.

That leaves plenty of time before a 3:30 p.m. kickoff in Las Vegas the next day—and time to return to Australia by Friday.

The long flights might be less of an issue than the time zone changes. The Super Bowl starts at 8:30 a.m. Monday morning Tokyo time.

To backpedal 17 hours then quickly advance 19 hours within the same week would be quite the feat, much less playing multiple concerts on both ends. But history suggests she’s physically capable.

Her concerts span more than three hours, without significant breaks or intermissions, and she prepared for the current tour by singing the entire set list on a treadmill daily, running for upbeat songs and lowering to a jog or speed walk for the slower ones.
