The result delivered McLaren's first one-two since Daniel Ricciardo and Norris achieved the feat at the 2021 Italian GP on what was a significant day for the team in their pursuit of a constructors' title.
Despite his stunning success on Sunday, Piastri has revealed his celebrations were fairly muted as he shared the story of what transpired on his flight home.
Speaking to Fox Sports, the 23-year-old said: “We had a flight back from Budapest that was significantly delayed.
“We were flying with a few of the drivers. Lando was there, Alex Albon and a couple of others.
“In our wait for the delay we got a cheeky Macca’s - I had a Big Mac.
“There was nothing crazy, just a couple of F1 drivers getting some burgers and nuggets, really.
“We were playing Monopoly on the way back on the plane. We’re all good apart from Alex Albon teaching us a thing or two about Monopoly.
“I got home at 5am and that was the celebrations. It wasn’t the most glamorous of afterparties, let’s say.”
