If the *A lounge finder is to be believed, we've got the following situation:

• Mont Blanc (Terminal 1B, Non-Schengen, 5-20:45) - Contract Lounge for LH and TK
• Salon Solano (Terminal 2, After Security 5-20:15) - Contract Lounge for SN and OS
• Le Patio (Terminal 2, Before Checkpoint Charlie, 5:30-22:00) - Contract lounge for TP
• Confluence (Terminal 1B, Schengen, 5-19:45) - Contract Lounge for LH

That being said, the *A lounge finder is by no means definitive, just a good start!

Safe Travels,
