MY information is that at least 1 B757 is coming. It will be two-class operating LPL-EWR-LPL and will be crewed by MAN B767 flight deck and cabin crew. The MAN based 767 will be operating MAN-CPT-MAN and will be the 2nd 'Big Boeing' to arrive due Sept/Oct 2006 with the B757 arriving Spring 2007 ready for the April launch of the EWR service.

Don't think it will be XLA's old machines as the 2 a/c destined to leave are only 104,326kg MTOM aircraft where as GSM will probably need 113,800kg machines as they maybe regularly going out at 79,500kg ZFW needing a full fuel load of 34,500kg to get to EWR with standard IFR reserves especially if the service is going to run year round with those notorious NY Area snowstorms.
