I'd definitely use a regional for your +1
If you're on CO metal, split yourself off the PNR, and apply the regional to your GF's itinerary. As the highest Plat, you can start to clear 6 days out on EUA. If it's not looking like it will clear, you can use a regional for yourself, but to me, it would be a waste.
