They were due to arrive in New York City the day before New Year’s Eve.  Granger said they were welcome to come the day of, but warned of the effects of jet lag even with instantaneous continental travel.  That being said, Draco was unsurprised to find everyone he believed to be going in the portkey lobby at the Ministry.  There was himself, Theo, and Pansy, of course, then Potter, Wealsey, and Ginevra Wealsey, as well as Lovegood and Brown.  Each of them had a suitcase of some kind, some more eclectic than others.
