As far as I know, both types of operation would need to apply for traffic rights to operate these routes. Whether or not these would be issued depends largely on whether there is spare capacity in the UK charter market. If it is for scheduled services, forget it. Interestingly enough, Icelandair managed to get traffic rights to operate a series of MAN-CPT charters.
Interesting handle TJ747, doesn't stand for Thomas Johansson, does it ?
