Singapore Airlines has a semi-official lounge in Jakarta (CGK) located inside the Plaza Premium Lounge. Here’s a review of the both the first class and business sections.
Once inside, head straight back, then turn right, walk through the main lounge (pictured below) and then turn right at the every end–you’ll see a Singapore Airlines sign.
There are no opening hours posted, but it is open at 3:00 am before the first Singapore Airlines departure until the last flight departs (late at night) and it’s inside a 24/7 lounge.
A great solo travel tip spotted this week on Live and Let's Fly.
