The Clooneys handed out noise-cancelling headphones to their co-passengers in case their six-month-old twins started crying, according to multiple reports.
Passengers travelling first class on a flight to the UK got headphones featuring the logo of Mr Clooney's Casamigos tequila and handwritten notes, according to the New York Post's Page Six. "Even (American filmmaker) Quentin Tarantino, who was onboard, wore the headphones," Page Six quotes a source as saying.
E! News accessed a photograph of the handwritten note, which read, "Our twins just discovered SQUAWKING!! Hope this helps make the flight a little quieter."
56-year-old Mr Clooney and 39-year-old Ms Clooney welcomed their twins Ella and Alexander in June this year.
As it turns out, the flight went off smoothly as "the babies didn't make a peep," a source revealed to Page Six.
"How thoughtful," tweeted one person. "Totally classy and respectful! For me, I'd rather them pass a baby to me (for a bit) to cuddle," joked another.
But not everyone was thrilled at the gesture.
"Babies cry. It's life. Get over it," commented one person on Twitter. "While it is super nice of them to do so, why do people feel like they have to apologize and appease people for taking your baby on a plane," wondered another.
