2 Questions as my screaming kids are preventing me from the time I need to look this up....

1. the enhanced e-upgrade email that went out, did that cover international destinations?

2. My first flights in 2016 are long haul AC, but sadly just booked...while I got an aisle, no preferred seats left (only in Y). Is there an APP, or some other notification tool, aside from checking regularly, to see if a certain seat(S) has come available (if a S.E. got their upgrade, etc. - I'm only 50K)...

Thanks!
