I have just seriously started to look into a RTW and am a little over-whelmed with all the details... I understand the basics, but could use help in a couple of areas. I have about a month and a half starting in the middle of Ocotber, and am not sure how many stops to try and fit it - worried about trying too much. The accumulation of miles - do you pick one airline, or are they accumulated for use on any of the members of the alliance? Cities to purchase the ticket - I have noticed that there is a pretty big difference in price between a couple of cities. I am currently in Spain, and am curious what some of the cheaper cities to purchase and then begin my trip from might be. Im looking at a four continent ticket, and any advice anybody could give would be much appreciated - cities, tips etc. Thanks
