With her cleavage on display, the Keeping Up With The Kardashians star certainly turned heads as she checked in at the terminal on Tuesday (11 March).
Kim's plunging LBD was teamed with a smart leather jacket and strappy gold heels, not to mention the (as always) perfectly styled hair and heavy make-up.
Did she have a hot date right before her flight?!
Competing for attention with her glam outfit was Kim's sibling Khloe Kardashian, who wore a skintight, low-cut black top and black skinny trousers.
A pair of sunglasses and bright pink pout finished off her A-list traveller look.
Their outfits were certainly in contrast to sibling Kourtney, who looked far more casual (and comfy) in ripped jeans and a striped shirt, even if she did up the glamour with a pair of stilettos.
The sisters and Kourtney's boyfriend Scott were all catching a flight out of LA to Miami, where they are opening a new Dash Boutqiue.
And, being one of America's most famous families, it's no surprise they flew first class, as seen in a Vine video posted by Khloe, showing Scott, Kourtney and Kim all engrossed in their mobile phones ahead of take off.
The stars' Dash store in Miami is located in South Beach. They also have stores in Los Angeles and New York, which viewers of Keeping Up With The Kardashians will have seen them visiting in the past.
So far, there is no Dash Boutique in London, although Kim did admit back in 2012 that opening a UK branch would be a dream come true. "We would love to set up a Dash store in London and we were talking about who would take what city and London was one of the options," she told BBC Radio 1. "We don't spend a lot of time here, so it would be fun. It's like our dream."
