The sisters - Kim, Khloe and Kourtney and their mother Kris Jenner find it funny to create false names for travel, the New York Post reported.
Kim's alias is "Ava Tar," possibly after the blockbuster 2009 film 'Avatar', Khloe travels under the alias of "Joe Dash," which is perhaps a combination of the first name of husband Lamar Odom's father Joe Odom, and their Miami and NYC clothing store Dash.
Meanwhile, Kourtney travels under the name "Betty White," and mother Kris is "Snow White".
"These are the Kardashians' names for hotels, car services, etc. I am sure this is what they will be checking in as if they come to New York for Fashion Week," a source told the Post.
