Hi all, I recently received the SW 50,000 points for opening a CC. I am looking to book 2 round trip flights in December, however, I'm not 100% sure I will be able to take this trip. If I were to book the flights with my points and then cancel, would those points go back into my bank of points that essentially dont' expire OR is it like any other booking in that they would credit me for the flight and I would have to use them within 1 year? Does anyone know?
