As the clock ran out at the Super Bowl on Sunday night, and the Philadelphia Eagles ran onto the field in New Orleans, confetti filled the Superdome and the team’s fight song, “Fly Eagles Fly,” blared over the speakers.
Chants of “E-A-G-L-E-S” came from all corners of the 83,000-seat stadium. But now, fans went into overdrive, dressed in beads and sequins, flapping their arms like birds, and hoisting one another onto their shoulders.
There was plenty for those Eagles fans to cheer as Philadelphia beat Kansas City, 40-22, stopping the Chiefs from becoming the first team in N.F.L. history to win three consecutive Super Bowls.
Lit with green lights, Eagles fans spilled out of the stadium whistling, high-fiving strangers and dancing to a drum band, as Chiefs fans walked by sadly and serenely.
Throughout the game, the excitement had extended beyond the field.
President Trump, who was a guest of Gayle Benson, the owner of the New Orleans Saints, watched some of the game from a suite alongside members of his family, including his daughter Ivanka Trump and his daughter-in-law Lara Trump. He was also joined by members of Congress, including Speaker Mike Johnson. In another suite, the former first lady Jill Biden cheered on the Eagles with help from her grandson, Robert Hunter Biden, among others.
As Taylor Swift, Paul Rudd and other notable Chiefs fans watched the game tensely, with things going poorly for their team from the start, high profile Eagles fans, including the actor Bradley Cooper, the comedian Kevin Hart and the actress Anne Hathaway, were spotted around the stadium cheering loudly.
“It was pure domination,” said Phil Minissale, 38, a beverage sales specialist who lives in New Orleans and grew up in Philadelphia.
He was wearing a feathery eagle mask, which covered up the tears in his eyes. “I’m emotional about the game,” he said.
Mr. Minissale said the $2,900 he paid for his ticket, which he bought at 2 p.m. on game day, was worth it. “Money comes and goes, but this is a magical night,” he said.
It was clear from the time the teams were introduced that the crowd at the Superdome leaned heavily toward the Eagles, and as those fans streamed out of the stadium following the win, a block party emerged outside, with devastated Chiefs fans forced to make their way through the chaos.
Shawn Laroda, 54, a retired welder who lives outside of Philadelphia, was outside the stadium with four friends puffing a cigar he brought from home.
“It came all the way here on a plane,” he explained, beaming.
He still couldn’t believe the game’s results.
“I think we’re going to take a few whiskey shots before going to bed,” he said.
Dahiana Torres, 48, a nurse who lives in Bradenton, Fla. and is originally from Philadelphia, was handing out green whistles to the crowd and screaming “Go Birds.”
She watched the game in a bar and then headed as close as she could get to the stadium where she had been for the last half-hour.
“I just want to stand here and cheer,” she said. “I mean that game was insane. We were the underdogs, and now we showed them that we are not the underdogs.”
Taylor Barber, 24, a teacher from Dallas, had a personal connection to the team.
“My cousin is an Eagle,” she yelled into the crowd at the top of her lungs, referring to Milton Williams, a defensive tackle for the Eagles.
She was wearing a T-shirt with his No. 93 on it along with knee-high green boots.
She and her two friends, who are also teachers in Dallas, were headed to the Eagles postgame party, taking place nearby.
They couldn’t wait to celebrate alongside the players. The plan was to out-party them, said Jessie Ulmer, 23, who was wearing a gold sequined purse in the shape of a football with gold cowboy boots.
“We are going to drink like we are the ones who won,” she said.
Other fans were on their way to celebrations in the French Quarter.
Brooke and Shane Felgoise, siblings who live in Baton Rouge and grew up in Philadelphia, were headed to Bourbon Street, where football fans had congregated all weekend for Mardi Gras-style street parties.
“I already called out of work tomorrow,” said Ms. Felgoise, 23, who works at a law firm.
They attended the game after their mother surprised them with tickets earlier in the week.
“I wish we could celebrate on Broad Street, but Bourbon Street will be fun,” said Mr. Felgoise, 19, a freshman at Louisiana State University. “There are so many Eagles fans here it feels like home.”
