CAX international Flights
Unlike the old days before Brexit, an international flight by an EU (GB airline obviously would be in this bracket) airline for intra EU route would just declare its intention freedom to conduct business in EU without Barriers. The Home Office would then need to provide Border Force Officers to cover that flight. These days new EU routes will need permission of the Home Office and IF they get permission, they‘ll (airport authorities) need to pay for the accommodation ie offices, X-rays, front desks, Secondary Examination area and all infrastructure that is in legislation. I don’t think Stobbart will want to pay that cost for possibility of a twice day E-jet.
