I booked one RT already for around $1k and thinking about grabbing another one... anyone know if you'd be able to change or cancel the second leg of the trip after booking (particularly after flying the first leg) since Alaska prices the legs individually? since I'd be nesting two RTs within three trips, the third trip is pretty speculative and would like to have some flexibility.

Just want to make sure I'm not gonna get banned by Alaska or anything if I fly one $400 business leg but don't fly the second lol
