Utifrån reglerna så känns det, ärligt talat, inte självklart vad som gäller:
First and Business Class Customers
Lounge access is allowed for First and Business Class customers traveling on a same-day international flight operated by a SkyTeam member airline or with same-day transfers between flights (domestic or international) operated by two SkyTeam members. Lounge access will be provided only at your departure and transfer airports, and not on arrival. First and Business Class customers can enjoy access to the lounge at the departure airport at least 3 hours prior to their flight's scheduled departure time.
For connecting customers, both the domestic and international flights must be operated by a SkyTeam member airline, and all segments need to be booked in First or Business Class. Customers traveling on domestic flights must have an itinerary comprising a transfer from a domestic flight to an international flight or a domestic flight to another domestic flight, followed by a transfer to an international flight.
