If there is C upgrade space available your SWU will clear immediately.
So only took 80 minutes on a call for the representative to process, but was able to get confirmed upgrade from DFW to SCL for May 2023. Only waitlisted on one short domestic flight to DFW on the outbound. The agent had to keep reaching out to a different department to complete the transaction, but glad she took the time to do so. Not all agents are as diligent and helpful.
