So, I called AA and they said that it was not an issue at all. Really no reason to do anything, and they couldnt change the ticket. But if I wanted , in the info that gets forwarded to TSA (?) they would change it to Mr. Just to be safe I also called BA. They said that they would submit the correction, could take 24 hrs. (the return flight was in 23 hrs, but she said it would be Ok.
On the return, since we had PA, we lined up to board right away, and yocheved'd ticket buzzed, and the screen said somethig like 'not allowed to board'.
Yikes.
Luckily there was a really nice Admiral Lounge agent nearby, who offered to look into it. Seems like when BA changed the ticket, they didnt properly reissue it. She researched the ticket #, and from there they were able to get Yocheved a seat. I didnt have much faith in the regular gate agent. He looked like the type that would tell me to call BA and have them straighten it out (and miss my flight).
