I'm trying to select seats for our flight that is now 6 days away. I have oneworld ruby status via American Airlines. The British airways app is letting me select seats, however, nothing further up than row 40 is available. I was hoping to sit further up and was wondering why I can't even see seats in other sections. My flight class is economy (NOT BASIC). Am I missing something here?

Thanks in advance for the help!
