U.S. Officials will be at MAN tomorrow and Thursday to discuss the next stages of US CBP.
The announcement of confirmed airports for CBP is likely to be in the next 4 months, with MAN highly likely and implemented by 2018 (2018 is due to the MAN facility being custom built in the extended terminal rather than shoehorned into an existing area of the terminals).
Heathrow unlikely to feature in this round due to the complexity of implementation such as mix of terminals and the large volume of staff that will be needed to handle the amount of pax Heathrow generates, but the U.S. Officials will also visit Heathrow to see if work can be done to implement CBP in the future.
