I agree that AA Plat challenge is the best way to maximize miles, but for RTW it is really more cost-effective to buy D instead of L considering how many hours of plane and airport time it entails. You gain a day at your destination by being in better shape after the plane.
Thanks for clarifying the LAX lounge. That will make it worthwhile. I had in my mind that Plats only got lounge access if flying J or F internationally, but my brain is mush at this end of the week

As for D vs L, some of us can't affort to pay 3 x the fare price, especially if for leisure. I will consider it if I can claim the price difference as a tax deduction if the trip is for business, but if not, then my holiday budget is better spent enjoying my destination rather than enjoying getting there.
