One thing I have learned re dealing with AA! Beyond expecting changes, that is.....

Since we often book FF seats from separate FF accounts and end up with separate record locator numbers for the same flights, on more than one occasion when there were changes in routing or equipment we ended up having our seats separated. Apparently the computer recognized us each as solo travelers and didn’t connect the names.

What I didn’t know for the longest time is when you book reservations under these specific situations you can contact AA and have then ‘link’ the record locators. At least then, if we end up having our seats changed, they change us both and we still end up together. It wouldn’t be the end of the world if we weren’t seated together as long as we’re on the same flights but it certainly is more convenient and ‘comfortable’ that way.
