Mostly crumbs now that the huge devaluation took place. (Lax-Eze in J 200k miles one way, Alaska still 45k on LATAM).
the only way I get value out of my miles is to book a crap routing and wait for a schedule change. Depending on who you get on the phone, you can change it to a better routing (or HUCA).
if the 5 day holds on awards are going away, it’s a net negative. I font know why they would announce it otherwise, there already is a 24 hour hold on paid fares.
