Indeed - Skyteam has always had a requirement that there be an international Skyteam flight on the same day in order to get access on a purely domestic flight.
any airline is free to set a more lenient lounge access policy for its own frequent flyers - but not for all Skyteam Elites - and UX abandoned this more lenient policy for its own elites many, many years ago
