How to use airline miles to fly business class (without even stepping foot on an airplane)

Business class. The dream of all who fly. With its flat beds, delicious food, wide seats, and pampered service, it seems the part of the plane reserved only for frequent fliers or those with deep pockets. At least, that’s what I used to think. Now I fly business class on all my long haul flights and I’m neither a rich man nor that much of a frequent flier (I don’t even fly enough each year for get elite status). So how do I get into business class then? I use the airline’s rewards system against them.
