Kim, Khloe And Kourteney Fly High

It's hard to keep up with the Kardashians! The jet-setting sisters all left home with their bags and headed to LAX airport Thursday, and our sources say they were en route to Miami!

The sisters have very different airport style; Kim stuck with sky-high heels, Kourteney grabbed a blanket for comfort and Khloe kept it comfy in a long dress.

We also like their different sunglasses style - Kim is oversized, Kourteney is cat-like and Khloe is channeling ... Elton John.

Looks like the next pics of these three will be on the beach! Wonder if Kim will let her famous booty get tan, or if she'll cover it up with a sarong as she's done recently ... much to the dismay of men everywhere!
