LINK. From October 28 passengers on one of BA’s two daily all-business class flights from London City to New York will no longer be able to avail of US immigration pre-clearance at Shannon airport. The carrier launched flights between LCY and New York JFK using 32-seater Airbus A318 aircraft in 2009 (for a review of the service click here). BA currently offers two daily all-business class flights – BA001/2 and BA003/4 – with both services routing via Shannon on the outbound journey for refueling, before returning directly from New York. At present passengers can avail of US immigration pre-clearance at Shannon during the stop, meaning that they arrive at JFK as a domestic passenger, thus avoiding immigration queues. But BA has confirmed on its website that from October 28 pre-clearance will only be available on flight BA001.
