Football fans started buying tickets as soon as they heard the lockout was over.
Ticket broker Stub Hub said the number of tickets sold Monday was double the normal daily average. Dallas Cowboys tickets were the second best-sellers.
Ten-year-old Cowboys fan Jacob Van Sant was all smiles after he saw the inside of Cowboys Stadium for the first time.
"It felt like I was famous because I got to walk through Jerry Jones' place," the Tomball boy said. "It was pretty awesome."
He and other fans across the world are celebrating the Cowboys' return to the football field.
"It's awesome, to say the least ," said Cowboy fan Louic Charpentier.
A native of Paris, France, he met the woman who would become his wife on a trip to Texas to watch the Cowboys play in their old stadium in Irving.
"It will be eight years in eight days," said his wife, Linda.
The couple said they look forward to making new memories in the new stadium.
"Super Bowl No. 6, maybe?" said Charpentier. "It's about time."
The Cowboys leave for training camp in San Antonio on Wednesday, but they'll return to a frenzy of fans ready for the first preseason home game in Arlington on Aug. 11.
"I hope I get to come," said Van Sant. "Now that would be cool."
A Cowboys spokesperson said the players will log more preseason practice hours on the field at Cowboys Stadium this year. It's still unclear whether any of the post-San Antonio preseason practices will take place at Valley Ranch, where the team normally practices during the regular season.
