BXP3 From PE (P) to J?
Sorry if it's been covered.
I have a ticketed booking R/T from DFW to HKG.
Outbound segment booked in Economy S Class - Used an SWU to upgrade to available C Inventory as S Class not eligible for BXP3
Return segment is currently booked in Premium Economy (P Class Fare) - Can I use a BXP3 to Upgrade from PE to J if C class becomes available?
