We were upgraded Thursday on our last leg to Hawaii, sfo to hnl. I purposely booked flights thru sfo for the cpu upgrade potential and it worked well.

we have a good chance for the return tomorrow. Both flights had Premium Economy sold as Economy Plus, so we are in good shape if it does not happen.

A question, tho, if I sdc to another hub where Premium Economy is charged, can you cpu into Premium Economy as well as Business? I can’t find any reference to this anywhere.
