Kim was spotted pushing North in her pram through the airport, along with Khloe Kardashian, Kendall Jenner and their mum Kris.
But while the sisters looked cool, calm and collected, Kris seemed a little harassed as she carried a giant bag, handbag and hefty stripy cardigan.
It's not clear where the Kardashian/Jenner clan were heading, however Khloe gave fans a sneak peek of baby North's airport getup.
Although Kim had kept the tot's face covered while walking through LAX, Khloe shared a picture on Instagram of her little legs and feet.
And, unsurprisingly, North was wearing clothes from the sisters' new Kardashian Kids collection!
Alongside the snapshot, Khloe commented: "North West rocking @kardashiankids #AirportSwag."
It's been a busy week for the Kardashians - but then what's new?!
Not only had Kim literally just returned from a TV appearance in New York when they jetted out of LA, Khloe and fellow sister Kourtney had just announced the name of their new show - Kourtney and Khloe Take The Hamptons.
As the title suggests, the reality series will follow the pair, plus Kourtney's partner Scott Disick, as they temporarily move from Los Angeles to New York to try and relocate their Dash New York store to an even better area.
The show will also see the girls as they struggle to set up their Hamptons pop up.
