When the trip gets close, get them a CLEAR trial which they can give up after the 3 months is up. That'll get them past the regular line. The best for your purposes would be an unbranded AMEX Platinum and her with a second AMEX Platinum card on the account. Then you both get in the club with 2 guests each.
What type of account is her secondary on and what card is it? She may or may not get access and guest privileges on her own.
My wife is going to be primary on one itinerary and use one of my companion certificates with the wife. I will be primary on my itinerary with the husband using another companion certificate. My wife now has global entry with Precheck so her itinerary should all get it, I'm the same so my itinerary will get it. Before my wife had global entry she always got Precheck when on my itinerary, same with any other travel guests I've had.
My card account is an Amex Reserve, my wife is the secondary cardholder with an Amex Reserve. Hers isn't tied to her Skymiles account like mine but all she ever has to do is flash it to the front desk person and they verify the name on the card matches her ticket and they let her in. I can bring both of the guests into SkyClub under my account and my wife can get in on her own.
