As the 1960s title of a British comedy film 'Don't Panic Chaps' ways will be found to circumnavigate the 18 million cap. For instance we won't include all the private charter passengers anymore in the monthly passengers - only a small amount in the context of the passenger numbers - but it all helps. For instance Arsenal flying to/from Liege for a European cup tie and premier league teams flying to/from Manchester, Liverpool, Newcastle et Al. Where there is a well there is a way.
