Oh my.

I think the suggestions made thus far are likely the best anyone here can do based on the information provided. I think you need to be more specific. How many Amex points do you have? Where are you traveling from? Are you getting married in 2007 or 2008? What other FF programs are you enrolled in, and how many miles or points do you have in them?

If indeed your nupituals are planned for 2007, I'd have to say that you are very likely SOL in scoring free seats with your suggested itinerary. If you have a ton of Amex points, you could possibly use the pay with points feature on the Amex site to book your travel, but at the rate of .01 per point, that is typically not the best use of your points.
