You Can Fly with Kim Kardashian and Kanye West If Ya Got $10k

Kanye West is a chatterbox on flights, and Kim Kardashian ... not so much -- which you would know if you'd scored a seat next to them on a private jet, like one non-celeb did this week.

Mazen Dayen was flying from NYC to L.A. on Tuesday for a business meeting when Kim and Kanye hopped aboard his JetSmarter. For those of us still flying coach, JetSmarter is like an UberPool ride ... but at 30,000 feet.

While Kim slept the entire flight Mazen tells us 'Ye talked to him about watches, cars and the soaring price of real estate in NYC and L.A. So, basically ... lots of rich people stuff. After all, they were on a private jet.

Mazen says it's not unusual to see celebs on these kinds of flights -- that is if you have the $10k for the annual membership.
