Fans were quick to comment on the post, with one writing: "Welcome to Greece!" while another wrote: "Sweet photo!" A third added: "Adorable and sweet."
It appears that Kate's entire family have gone out to Greece.
On Sunday, her brother Oliver Hudson shared a post on Instagram which was captioned: "It's time to go… summer," indicating that he was preparing to join his family at the airport.

Kate has gone away to Europe with her boyfriend Danny Fujikawa and her three children – including daughter Rani, two.
The doting mother and Rani were pictured in a sweet snapshot posted on the star's Instagram account ahead of their trip, showing them hand-in-hand on the way to the airport.
Kate's toddler looked adorable wearing a unicorn face protector and a face mask.
In the caption, the star wrote: "Been since March 2020 and now it's time to roll little lady. We got this."
Goldie and Kate are incredibly close
It is unknown whether Kate and Oliver's younger brother Wyatt Russell has also joined the family on the trip.
Goldie's youngest son is notoriously private but delighted fans earlier in the year after announcing the arrival of his first child – a son called Buddy.
Wyatt shares Buddy with wife Meredith Hagner, who has a close relationship with her husband's famous family.
Buddy is Goldie's seventh grandchild, and while he is the youngest at the moment, Kate has previously admitted that she hasn't ruled out having another child in the future.

After being reminded that his younger sister had previously joked that she was considering having another child to beat her brother, Oliver said: "She can have that win. I’ll pull up at the finish line and she can take the win if she wants it."
