Thanks so much for the info everyone!

This will really help me pick my flights (and use the most AA codeshares as possible to maximize the miles and points). I was really hoping to be able to experience CX, but the lack of miles may turn me towards AA unless there is a codeshare on the route. I'll really make sure to avoid IB!

I thought that the LONE booked into M class because I was looking on Fewmiles' AAdvantage guide site, where it says that M is for ONE and L is for promotional fares, seat sales and webspecials. Of course the fact that an LONE books into L class makes a lot more sense!

Sorry for the newbie questions, all of this can be so overwhelming, even when spending a lot of time trying to figure it all out!
