"We're playing some of our best hockey now," Jenner said. "We're feeling good in the room, we're feeling confident every night going into a game."
Andrew MacDonald had a goal and an assist for Philadelphia (35-25-11), which lost for the seventh time in eight games (1-6-1), including four of five at home. Claude Giroux and Shayne Gostisbehere scored, and Alex Lyon made 18 saves in relief of starting goaltender Petr Mrazek, who allowed four goals on 10 shots.
The Flyers said they felt they weren't ready at the start of the game, and coach Dave Hakstol shouldered the blame.
"Their team was a little more ready to play and that squarely comes to me," he said. "I thought their team was a little more ready to play in that first 20 minutes, and that can't happen at this time of year."
The Blue Jackets took a 2-0 lead on goals 11 seconds apart by Bjorkstrand (9:41) and Jenner (9:52) in the first. Giroux scored at 11:34 to make it 2-1, then Atkinson tipped a shot by Zach Werenski past Mrazek with 1:52 left in the period to put Columbus ahead 3-1.
After Gostisbehere scored on the power play 14 seconds into the second period to make it 3-2, Atkinson beat Mrazek off the rush from the right side at 3:23 of the period to give the Blue Jackets a 4-2 lead.
"I think it stopped their momentum for a little bit," Columbus coach John Tortorella said of Atkinson's goals. "They get within one, bang, we score one. They get within one again, bang, we score one. I think it just slows them down. Because if they start mounting the momentum and we don't score and they keep coming, who knows what happens. Maybe we get too nervous because they're really coming. It's a really big part of the game, scoring those two goals to get a two-goal lead established again."
The Flyers got within 4-3 on MacDonald's goal at 12:23 of the second, but Atkinson finished the hat trick with an empty-net goal at 19:59 of the third.
