does associated 'B' domestic fare carry over from PPlus booking?
 

I'm considering doing SYD->SFO->RDU in PPlus. The domestic legs of an R or A-fare ticket appear to book into B. Does anyone know if that 'B' fare is treated consistently for things like same-day changes, auto-upgrades for domestic segments, and whatever other things the fare class might be used for?

This specific instance revolves around my wanting to very likely do a same-day-change once I arrive back in the US. If UA treats my ticket as if it were booked into B, the availability is far better than if it's booked into something else.

And while it would be perfectly logical to assume that "because it looks like it's booked in B, it will act like a B fare" .. we all know that's not always a safe assumption!

Yes, if booked as a single fare component, you are entitled to all the rights and privileges of a "true" B fare, including now free E+.

I am NOT doubting you this... but is there some detail about this or a thread? I can't see one.

I have preached for a long time I thought it was silly UA did not allow for non elites on full Y/B faresto have to pay additional for E+.

It's in the wiki of https://www.flyertalk.com/forum/unit...xperience.html - not sure if documented on the UA website. It is probably intended only for delegated segments of PE fares, but in fact works for anything confirmed into B. It does not apply to Y.

The B are and E+ access was explicitly stated in the early materials -- as captured in the wiki of https://www.flyertalk.com/forum/unit...xperience.html. Can not find it in the present materials but may be buried elsewhere.
