Within North America/Sun destinations, Premium rouge
is business class. It books in to the same fare classes, and if they swap mainline for rouge, you'll be moved from mainline J to Premium rouge, and vice versa.
That being said, the question is unclear, and it would be helpful if [MENTION=10105223]Kerrilyn Short[/MENTION] would post more details about the route and flights.
