No problems getting in to the I Mosaici lounge with BAEC status (and AY flight). Entrance is a bit low-tech, there's no BP scanner, instead the attendant writes down your FFP and flight details. She also seemed to insist that my status must be printed on my BP (which it was, so I didn't need to question the point further). I don't know what would have happened otherwise, so best to always see that status gets printed at checkin I suppose.

The lounge had quite ok seating, not crowded at all when I was there. Food was sandwiches, pastries and fruits, and there was what appeared to be a decent bar. The bar is not self-service, so I would assume it can be slow at busy times, as everything including coffee, water and juice had to be fetched from there.

Otherwise, not a whole lot to do. Newspaper selection was not very large, and wifi is not free. There was a sign saying they are planning to make it free, so that might change. Myself I don't quite understand why they don't just make it free, instead of announcing plans to do so, if they have the equipment installed and have made the decision. Maybe they just don't have enough bandwidth in place yet, or are bound by terms of a third party provider. A couple of computers in the corner which I assume are free to use.
