I went to the OW RTW site and constructed an itinerary that showed a price. I went to the final page to see if it would be able to be paid online at which time it was pushed to BA as the first segment is on BA. I only found this out when BA sent me an email about a schedule change. I did not pay for or enter credit card information . After a couple attempts at contacting BA reservations (U.S. number) I couldn't receive any information about if this was a hold and for how long but only that they would need to investigate about a "change fee" and could not/would not cancel the reservation. My preference is to use the AA RTW desk and make changes before purchase. This trip also populated in my trips on my AA account which I would like to go away to prevent future issues.

My questions: Will this automatically expire and I can construct a new intinerary? Any need to be concerned BA wants to collect a fee?
