3. Turkish Airlines Business Lounge at IST (Istanbul)
One of our absolute favorite business-class lounges in the entire world is the Turkish Airlines Business Lounge at IST. Eclipsing the old business-class lounge at Ataturk, this new business-class lounge is a huge, open-air space across 2 floors. This is an impressive lounge with bells, whistles, and Turkish flair. The entrance featured a self-playing grand piano, as well as peripheral seating. In addition, there are hot and cold teas in separate spreads in the Tea Garden, all of which had their region and main flavor profiles described.
