I'm considering an Emirates First Class award ticket from Dubai to NYC . It's around 25000 miles more than the biz class award ticket.

Question

1) Will a First Class award ticket give me access to the Emirates First Class lounge in Dubai? Or is that only for revenue FC customers?

2) Is FC really that much better than biz class (this is on theA380)? Emirates Biz Class is excellent as is.

Thanks!
