Trying to help my mom with the miles & points game. She normally flies to Hong Kong once every other year on Cathay Pacific (the only FF account she has thus far) but she's flying to Europe in a couple days on Air France (V fare), and a domestic Delta basic economy (E fare) flight. I was going to create and bank these miles to AS, but I read that they're ending their partnership with AF on Apr 30, 2018 so my mom won't be able to get miles credited on her return flight (in May).
