You can ask to be upgraded, I mean "if you dont ask, you dont get!!"
However you will most probably be rejected on the basis of the class of your ticket. ie: you purchased the cheapest internet fare available.
However if you are friendly with the customer service staff at your intended departure point this should never be a problem.

Ps:You gotta love business class, cant wait to try out the new menus!!
