I guess that in my post, I should have stated that yes that is what the OW supervisor said. However, I've traveled enough to know that even with one agent telling you something it may not happen when it actually comes time to do so. So what I did, as I normally would in this type of situation, is I had her document the record and had the fare stored. These at least will give me a good fighting chance in case she was wrong. As stated by another poster -the exception seems to be for issuance of tickets in Canada and the U.S. from ex- any other country. Apparently this is still in the rules.

I do wish that it was easier to get 'print outs of the rules' Does anyone have any good sources?

To the point of the other poster - and as I stated in my original post, BA would not allow the one stop (not the gateway) in the U.S. Whereas AA allowed it and ticketed it. Even the agents aren't familiar with all of the rules or at least have different interpretations of them.
