700,000 miles in the bank??? FIRST CLASS! No question. Unless you're planning some big family trip and will need those miles soon, burn them and treat yourself. Fly out of LAX or SFO to get the longest ride in international F, but go through ORD if necessary to get the new F suite at least one way.
Life is short. Go First Class when you can, and with 700,000 miles sitting around, you can.
