I thought it was an error fare, but appears legit. YQ is complete...
Great deal - Will probably make a great X-Mas gift (spend a Weekend in Milan, then head to NY for a Week)
Key Fare Rules:
TICKETS MUST BE ISSUED ON/BEFORE 23DEC 11.
PERMITTED 07JAN 12 THROUGH 31MAR 12 ON THE OUTBOUND
TRANSATLANTIC SECTOR.
TRAVEL FROM INBOUND TRANSATLANTIC SECTOR MUST COMMENCE NO
EARLIER THAN THE FIRST SUN AFTER DEPARTURE OF THE OUTBOUND
TRANSATLANTIC SECTOR.
STOPOVERS NOT PERMITTED ON THE FARE COMPONENT.
Update:
Looks like it's a fare war / price match.
Jet Airways is even cheaper, Skyteam (Alitalia non-stop) has a sale, so BA matches.
