LOL, ok, I do see the CS+ that you found:


[KVS Availability Tool 6.1.2/Diamond - SNT: Awards/StarAlliance/JP-ANA-SP1]

PHL Philadelphia Metro / Philadelphia Intl PA US = PHL TTN [KPHL]
MAN Manchester Intl UK [EGCC]
TUE 05 Apr 2011 | 1 Seat

Carrier Flight From Depart To Arrive A/C St Availability
--------- ------ ---- -------- ---- -------- --- -- -------------
US 734 PHL 20:40 MAN 08:40 +1 333 0 FS/ CS+ YS+

I have looked at a bunch more flights and still have not seen any other CS+ offerings from US Airways. How did you find that???

Also I read you FAQ Q&A #48 on associated fares and classes. Is there a way to find a fare for a CS+ then? Use your example, if you would.
Thanks so much, I am getting the hang of it...
