HOUSTON (KTRK) -- It didn't take long to spot Houston Texans fans headed for Mexico -- a Saturday morning flight was packed with Houstonians wearing their gear, excited to visit Mexico City.
Officials estimate that as many as 15,000 Texans fans could make the pilgrimage south, including Mayor Sylvester Turner, who arrived with several other city leaders over the weekend.
"We've been counting down the days and are excited to support our Texans in Mexico City. I've never been," said one Houstonian.
For some, their trip is a once-in-a-lifetime opportunity.

"It's an all-expenses paid (trip)," said Debora Bloch.
Bloch and her husband were lucky enough to win tickets to the game and a trip to Mexico thanks to an NRG Facebook contest.
"Actually, everybody that I talked to were like, 'I signed up for that, you won?'," she said.

While the game is not until Monday, there's plenty to do. NFL Fan Fest is hosting events throughout the city this weekend.
On Saturday evening, the Texans cheerleaders put on a performance at a local mall in historic Coyoacan, Mexico.
"Mexican people are just so passionate, not only about futbol but American football, so the Mexican NFL has done an awesome job of including everyone with the Fan Fest and the play 60, so we are just excited and honored to be here," said Texans Cheerleader Antonieta.
The Mexican government estimates the economic impact from Monday night football will be $80 million.
