SkyTeam Elite Plus
Regardless of their travel class, SkyTeam
Elite Plus members traveling
on, or
connecting to/from, a
same-day international flight operated by a SkyTeam member airline have access to a lounge. Lounge access will be provided only at your departure airport and transfer airports, and not on arrival.
For connecting customers, both the domestic and international flights must be operated by a SkyTeam member airline. Simply present your boarding passes and a valid Elite Plus membership card for the lounge agent to validate for admission.
