I am a Turkish airlines Miles and Smiles Elite member. Next week I have a trip from Berlin to Istanbul flying Turkish and then an Indigo airlines flight to India from Istanbul
Would I still be able to use the Miles and Smiles lounge at Istanbul? Irrespective of whether Indigo is a Turkish partner airline my first leg (Berlin to Istanbul) is definitely on Turkish airlines. Would that count for lounge access?
Edit: Indigo is NOT on Star Alliance. However Indigo seems to be a Turkish partner of some sort? See here:
