Scott Disick took his son Mason on a boys' trip to New York and Miami for Thanksgiving weekend.
The 'Keeping Up With The Kardashians' star shared photographs on Instagram of himself and his seven-year-old son standing in front of the British Airways Concorde jet at the Intrepid Sea, Air & Space Museum in New York on Friday.
Scott captioned the picture: "Take off."
Later he posted a photo of himself and Mason standing in front of a luxury helicopter in Miami, captioned: "We got the moves."
The father and son were also spotted walking on the beach together on Sunday, according to E! Online.
Scott's other two children with ex Kourtney Kardashian - Penelope, five, and Reign, two - remained in California with their mother.
But just before he left on his trip Scott posted an adorable video on Instagram of him enjoying time with his daughters and sharing a friendly embrace with Kourtney.
Scott, 34, is now dating fellow model Sofia Richie, 19, who also spent the holiday back in Los Angeles.
She was spotted buying a take away meal by herself on Thanksgiving Day.
A source recently said Sofia, daughter of singer Lionel Richie, has been a great influence on Scott since they began dating a few months ago.
The insider said: "She's been great for him. She's made a big impact on his life and hasn't partied at all since they met. They've been travelling together to Mexico, New York and Venice and just hanging out. His friends adore her and nobody notices the age difference. She is very mature, she grew up in Hollywood and has always been in older situations. They seem really happy."
