Do you mean awards? One or two? Because you can just buy tickets with money now. If you are talking awards and get one J and one F expect your companion to be peeved if you are the one in F and he or she is in the worse seat.

And really weigh the value of F vs. a J ticket. When the 777 was the old bathtubs in J and still had F, F was maybe worth it (it was for me).

Now for a slightly better seat and food and lounge those miles or $$$ can get you more (especially paying cash - a few hotel nights in the Peninsula and gourmet meals for the price difference makes paying for F a mug's game).
