While I'd agree their premium LAX - JFK is probably best in class, especially with access to the flagship restaurants, from SFO, I'd rather choose Mint these days. When AA first introduced this route, you didn't have all the free upgrades, and unsold seats would go empty. Now, it seems like you can book J on miles, and upgrade to F. Not interested in paying for it anymore.

While Mint, as far as I know, you can't cheese.
