She's certainly built a lot different than her sisters!

Kendall Jenner made a mad dash through the Burbank airport today, and the aspiring model proved she's got what it takes to make it in the business by rocking teeny jean shorts and a crop top that showcased her unbelievable bod!

We wonder how sister Kim Kardashian feels about Kendall having the hottest body of the family these days?!

The high schooler was traveling with dad Bruce Jenner, brothers Brody and Rob and sisters Khloe and Kylie. We don't know where the clan was headed, but Brody snapped an Instagram pic of the whole group on the plane, and - gasp! - they fly coach!

If Kimmy K had come along for the ride, the whole group would have flown private!
