join us at CES in Las Vegas? Delta is prepared to hook you up with 30 minutes of free in-flight WiFi on all of its flights to and from LAS beginning today. If you're flying in from the West Coast, that should have you covered for most of the trip. Otherwise, it's at least long enough to download your email or check to see if that farmland below is in Kansas or Nebraska. And if you opt to use social media during your flight, go ahead and throw in the #EngadgetCES as you rave about being able to tweet from the sky.
