One of the things that makes sapphire worthwhile is on most airlines, sapphire does give you extra benefits that you'd "normally" only get with emerald. For example, I have QF Gold, and quite often, I would get fast track and extra baggage...

It's probably a good place to post the extra benefits you'd get - I'll compile a chart if there are too many Could you post the benefit, the airline, the class and the airport and terminal you're flying from.
