Let us suppose Northolt was opened to commercial passenger traffic for a few years. Which airline would likely be the primary beneficiary given the current physical constraints such as runway length and no significant expenditure on transport links (ie no people transit or new roads) ? Would the biggest beneficiary be Flybe by any chance, in the hope of pinching some traffic from BA and Aer Lingus ? Could this therefore all be a bit of rather subjective public spin by a company with very specific interests ?
