It would be nice if there were a small for-pay lounge open to flyers on all carriers. Members with appropriate status in any and all programs (e.g. not AA elites but Admirals Club members) could then get in for free (paid by their plan as with some contract lounges). It could also serve Priority Pass holdres. Or it could be totally independent and even AC Elites pay on a per-visit basis.
Not that it's likely to hapen, given the lounge situation at YOW. My point is that it's not dependent on AC.
