I'm flying JFK-SIN-JFK with a 12 hour overnight stopover in DXB.

It's an F ticket, but my JFK-DXB segment is in J (availability I assume).

Any thoughts on how to spend the 10 hours? Is the F lounge open 24 hours?

Does Emirates take care of it's F pax with long layovers?

This will be my first trip on Emirates, and my first in International F - I'm looking forward to it - but not my 3:00am departure from SIN...
