Eric the 'easy' bear tells me that the combined phone sales/customer service for easy and Go will be in easyLand. Management facilities are being sought elsewhere, probably between Luton and Stansted.
Any move too far away from Luton/Stansted would require considerable additional costs to relocate employees.
Reduced passenger through put at Luton would cause the airport charges to rise, the more they pass through, the cheaper they become.
The big problem for the combined easy-Go group is finding additional usable slots at Gatwick and Stansted, both are very rare, temper this against the public statement that the local transport infrastructure around Luton will not support massive expansion of services from Luton in the medium term. You have a dilema.
easy expect to fly 400,000 pax between Luton and Paris in the first 12 months of operation, sales are going very well, so it would make real business acumen to withdraw flights from Luton Bearport!
