Fixed dates are tough... But this is the best I could find:
Monday June 3:
AC 344 Toronto (YYZ) - Philadelphia (PHL) 16:40-18:14 E75 (Y only)
US 722 Philadelphia (PHL) - Dublin (DUB) 21:00-08:45+1 B767 (J/Y available)
Tuesday June 4:
LX 401 Dublin (DUB) - Zurich (ZRH) 11:20-14:30 A321 (J only)
LX 1842 Zurich (ZRH) - Athens (ATH) 21:05-00:40+1 A321 (J only)
or
LH 979 Dublin (DUB) - Frankfurt (FRA) 12:10-15:15 A321 (Y only)
A3 833 Frankfurt (FRA) - Athens (ATH) 18:00-21:55 A321 (J only)
Tuesday June 11:
TK 1844 Athens (ATH) - Istanbul (IST) 21:50-23:10 A321 (J only, hotel provided for overnight)
Wednesday Jun 12:
TK 1975 Istanbul (IST) - Dublin (DUB) 07:30-10:05 B737 (J only)
US 723 Dublin (DUB) - Philadelphia (PHL) 11:10-13:45 B767 (J/Y available)
AC 347 Philadelphia (PHL) - Toronto (YYZ) 18:45-20:16 E75 (Y only)
The bulk of the flights are with US Airways, Swiss and Turkish in Business Class. So Scamcharges should be minimal. With fixed dates, it's virtually impossible to get any award seats in J, but there still seem to be seats available for TATL between Philadelphia and Dublin.
Of course, you can always redeem in Y, but that's not worth it. Good luck!
