To clarify the prioritization, does booking a premium economy ticket give any upside to upgrade priority? I see that the fourth category is booking class, but wasn't clear if that's only within a given cabin (i.e. Y > G) or would also be the point at which W would come into play vs. Y fare classes
Just trying to understand if there's any benefit to booking PE vs. Y besides the higher EQM, seat, etc. (assuming no complimentary upgrade from Y to PE)
