So,

I have a F award seat on JAL LAX-NRT, continuing my journey to CMB on CX First/Business. I also have the choice to fly CX F which - as awesome as it is - I have flown before. The tricky thing is that to try JL F I have to cut two full days in Sri Lanka, effectively shortening my vacation there.

Now: is this worth it just for the sake of trying a new F product? Does JL release F availability closer in? All other dates appear to be not available.

Thanks!
