The photo showed the football mom getting a warm welcome as she joined a slew of Chiefs fans on a plane that was headed to Frankfurt, where the team plays on Nov. 5.

The woman of the people wore a denim jacket with her son’s No. 87 on it, along with patches of stars.

But some fans couldn’t believe they were seeing the NFL’s most famous mom headed to economy seats on the commercial flight.

One high-flying spy told Page Six, “People were surprised she was in coach!”

Perhaps one reason for the commercial travel is that Travis’ superstar girlfriend, Taylor Swift, who has her own private jet and is not afraid to hop in it to see her new man, apparently won’t be making the game.

She’s said to be prepping for the next leg of her Eras tour. Swift performs next in Argentina on Nov. 9, before heading to Brazil and Japan.

Swift, 33, previously attended a number of games with her beau’s family, plus some starry pals like Hugh Jackman, Blake Lively and Ryan Reynolds.

Donna is said to be arriving in Germany even before her son and his squad for the game.

Reports have said that Travis’ family is “overwhelmed” by all the fanfare surrounding his romance with Swift, according to TMZ. The outlet reported that family members are “watching what they say these days very carefully” and are “under a microscope” with their phones “getting blown up nonstop.”

But they’re “dealing” with it all because “they’re happy Travis is happy,” sources told TMZ.

The “Love Story” singer has sat with Donna and spent time with Travis’ family at games against the Jets, Broncos and Chargers, we’ve previously reported.

When asked about Swift during a “Today” appearance, Donna, 71, said she didn’t “like to talk about” their time together.

But she did add briefly that meeting the pop star was “OK,” and commented, “I was in the boxes with her. It’s another thing that’s amped up my life.”

The couple hard-launched their headline-grabbing romance in New York multiple PDA-filled outings and an appearance at “SNL.”
