90% of the time I'm in a SkyClub is because I'm flying biz class. The other 10% due to SkyTeam Elite+ on international itinerary. I don't have a Delta credit card and would never burn a choice benefit selection on SkyClub access. I have the Chase Saphire Reserve Visa and get Priority Pass Select as a benefit. My home airport is PDX and the Priority Pass benefit has paid for itself multiple times.
