US Airways Dividend Miles - US Baggage Charges

Flying soon with partner from UK - Manchester to Las Vegas via Philadelphia on US Airways after stopover on to Phoenix then stopover and on to San Diego.
After final stopover return from San Diego to Manchester via Philadelphia.
All flights on same ticket.
Last year had a similar US trip on American Airlines with stopovers and paid no baggage fees for internal legs due to the trip being treated as UK/US one ticket trip and recall a few years ago another trip on the same basis.
This time baggage from UK/Phil/LV and SD/Phil/UK is free but LV/Phx and Phx/SD legs face being charged $25 per bag x 4 = $100.
Was I just lucky previously or has anyone avoided US Airways charges due to having one similar through ticket?

Do you have any Star Alliance status?

None at all unfortunately!

justdennis, welcome to FlyerTalk. As this appears to be US Airways specific, let me move this to that dedicated airline forum for more discussion. Ocn Vw 1K, Moderator, TravelBuzz.

Fee is per check-in baggage. Since you will be checking in baggage at the following airports:

MAN
LAS
PHX
SAN

If you would have checked luggage in MAN all the way to SAN and from SAN to MAN hen you wouldn't need to pay in LAS or PHX

Thank You
But the reason I ask is that on two previous occasions I have escaped these charges on similar mid flights by reason of one itinerary ticket covering all.
.
Guess I've just been lucky before...

By that definition you would pay only once for whole round trip?

No - didn't even make one payment previously.
That's why I invited anyone else to advise if they had such an experience.

There were recent changes in luggage allowances on many carriers. I know LH changed it recently. Not sure about US. They got more and more strict.

I remember *G would get you 3 check-in now it is 2. Go figure.
