Hi Elenita! An unaccompanied minor would generally not be allowed in the club. All guests must be accompanied by the person who is the actual member. From the Delta website today: "Individuals must be at least 18 years of age for Club membership or access without a responsible, supervising adult." There will always be someone with your UM though. In larger airports there is generally a separate waiting area for them, away from the general passenger area, when they have longer layovers.
They can page, depending on who is working
Generally Delta does not offer minor to Club access unless you are Diamond or you have paid for extra guest.
Try this number. +1 800-496-2225. They can at least help direct you to the right people!
