I have several questions:

1. If I book this on my AMEX will I get 5:1 points?
2. I need to book FOUR RTW tickets, 2 of them are identical itineraries. The other two are slightly different from each other and 80% the same as the two identical ones. I have all the dates, flight #s and times for all four tickets. Should this be as simple as finding an agent to read it to?
3. Can I call the AA EXP desk and do it through them?
