Haven't seen anyone mention this yet, but C+ is no longer classed under the "Premium Economy shelf" for TATL and TPAC flights. This means when you search on Google Flights and other OTA's, C+ flights no longer shows up under Premium Economy when searching for TATL and TPAC flights and they will only present true PE products. Had wondered why Google Flights had stopped showing C+ options recently on TATL/TPAC PE searches.
