Didn’t feel like I really had enough time for the Plaza Mayor lounge even though I am a Priority Pass member, But it turns out I could’ve because boarding was late. So an hour and five minutes gate to gate; with my original scheduled arrival time into MAD and onward departure it would have been pretty anxiety producing. Glad my TATL arrived early.
