Terminal 3's Mingalar Sky lounge is the domestic option. The airport lists it airside near Gate 25, open 06:00–19:00. Priority Pass lists it on the 1st floor near Gates 34–35 and at times has shown a much shorter hours window, so treat hours as verify-on-the-day. Amenities are basic (soft drinks, Wi-Fi, TV); showers are not advertised for this room.
