Kourtney Kardashian and Scott Disick were noticeably absent from the Kardashian family's big vacation to Thailand and now we know why!

The couple didn't travel to Asia because Kourtney and their two kids, son Mason and daughter Penelope, allegedly came down with a cold and were too sick to fly across the globe, E! News reports. 

While the family enjoyed lots of fun adventures, including zip-lining, playing with elephants and beach time, Kourtney and Scott laid low at home in Los Angeles. The couple, however, recently enjoyed a getaway to Santa Barbara while their family (including Kim Kardashian, Khloe Kardashian, Kris Jenner, Bruce Jenner, Kendall Jenner, Kylie Jenner, Brody Jenner, Brandon Jenner, and Leah Jenner) was away.

Kourtney was certainly missed on the trip, but she wasn't the only Kardashian who stayed home. Brother Rob Kardashian also skipped out on the vacation, as he did during the family's getaway to Greece in 2013. 

The Kardashian-Jenner family vacationed in Thailand earlier this week, where they also stopped by an orphanage, and the family was seen arriving back to LAX on April 2. 

While making their way through the airport, Kris and Bruce sparked rumors they might be back together when they were photographed holding hands.
