For her solo flight, Kaia was able to showcase her signature off-duty model style, which often has a sporty edge.

She kept cozy in a psychedelic, color-blocked sweater that featured cohesive shades of yellow and brown.

Gerber paired the eye-catching sweater with some high-waisted denim jeans that accentuated her already length legs.

The daughter of Cindy Crawford slipped her feet into a pair of special edition Adidas kicks that featured blue and red velvet stripes on the heels.

Her shiny shoulder-length hair was parted down the middle and she kept her mouth and nose concealed behind a face mask.

Upon entering the buy airport, Kaia rocked a pair of black designer shades that she later removed, while going through the airport’s metal detectors.

In case she got cold, the Vogue covergirl brought along a trendy, oversized plaid blazer.

Gerber packed ultra light for her flight as she walked through the terminal with her belongings in a black canvas bag and her essentials in a cross-body purse. 

Once she arrived to her destination, Kaia took to Instagram to post a belated birthday message to fellow model and pal Hailey Bieber, 24.

‘Okay I know I’m a day late BUT when I tell you it took 24 hours for me to find this picture I MEAN IT,’ wrote the brunette beauty in reference to a photo of her and Hailey she shared with her 6million followers.
