iCloud documents encrypted in flight?

[imrazor]

I think I know the answer to this given Apple's stance on privacy, but I'd still like to be sure. If, for example, I am working on a Pages document on my Macbook on an open WiFi connection, and save it to iCloud, is it encrypted en route to the iCloud server?

In other words, is there any chance of having documents intercepted while working at a Starbucks or other eatery?

I don't think so.
