Kardashian Sisters Bid Farewell to the Big Apple 11/30

Finished up with a brief trip to the Big Apple, Kourtney Kardashian and son Mason joined Kim and Khloe while making their way through JFK Airport in New York City on Tuesday (November 30).
The E! reality sisters passed through security ahead of their outbound flight, with Kourtney helping little Mason walk down the terminal treadmill before he tried his best to run down the moving pathway by his lonesome.

The trip back to Los Angeles comes as Kim, Kourtney and Khloe made press rounds in NYC to promote their first book "Kardashian Konfidential" which hit stores this week.
After visiting WB11, the gals made a stop at a local Barnes & Noble, with Kourtney tweeting, "Wow! Just pulled up to our first book signing ever at Barnes+Noble! Thank you so much for everyone who have come out to see us! We r blessed"
