So long as you're willing to pay for a Single Visit Pass, Delta-operated SkyClubs (separate from partner lounges) are accessible to you.

The Friday the 23rd flight is the Friday after Thanksgiving. That's not a normal Friday for travel and may have different chances.
Of course all flights are hit or miss. Sometimes over holidays DL offers cheap buy-ups and the seats could fill with paid FC. Or the cabin could be empty. I've had both over the past years traveling over Thanksgiving and Christmas where I've seen empty FC seats and where I couldn't even clear with an RUC because FC was sold out with paid FC. On my trip to DTW over Christmas, FC was only $90 more round trip over economy. Given that I was using the companion certificate, an additional $45 per person for F over economy was an easy decision.
