The brochure I got with my card states it provides complimentary companion airline tickets and upgrades for international travel on select airlines from select cities, and special amentities and rates on select cruises, tours and fine hotels and resorts worldwide.

I called Citi and they said the best thing to do for complete details (other than waiting for their marketing brochure to arrive about it) is to call Virtuoso directly at 1-877-285-4201. This line is supposed to be set up for World Elite cardholders. Or you can call Citi and ask them to transfer you to them.

I'm curious what the minimum fare classes, and list of "select cities and airlines" are.
