Lufthansa is in the process of re-launching a wifi service for trans-atlantic flights! This is both great and terrible news. It is wonderful if you need to be in touch...but terrible if you want to have no choice but to be out of touch!
Pricing is not inexpensive at EUR19.95 for 24 hours of access...but perhaps not unreasonable when you consider where you are logging in from.
I guess you need to fly trans-pacific to be 'out of range!'
