Yes, I understand the economics. I do use AA RTW to actually book. However in the past I have priced about 15 or so different options for each booking. The oneworld tool was buggy but it got me the information I needed to know before calling a human. Mainly alerting me to stupid mistakes that I was making and showing me different flight options. Now it is just not populating the different stops which it did before. Oh well, I will wait and try again. Thanks.
