While we are on this subject, I'd appreciate confirmation that the purchased segments do not have to fall within the long haul constraints. That is, one can purchase LHR-DXB-LHR as two extra segments even if one already has LHR-CAI-LHR or can have two extra trans-continental segments within North America or Australia (within the limitation, of course, that the purchased segments are not in the continent of origin). Correct?
