Upper Class extras

Hello everyone! Could some tell me if you are traveling upper class from Gatwick what extra perks do you get if you have an economy passenger flying with you? Can they check in at the upper desk...use the fast track security...and have access to the lounge? Thanks

Welcome to the site y)

Check-in at Upper *with you*, yes.
Use Fast-Track... No, not really (but they'll normally allow it if you look like you're "together")
Access the lounge with you, yes

Thanks for your quick reply! I thought as much that's how it was.
