I would like to keep those double nights in the Far East and West coast though.
The double night thing wouldnt have been half as scary if BASSA knew where to look in scheme for the limits. If Virgin dont do a single night somewhere you can be assured that theres a good reason, either its over the legal limit, or so close that the disruption simply isnt worth the saving. On that basis its only JNB and CPT at significant risk.
It is worth noting though that Virgin crew do significantly more cabin/meal prep prior to boarding so their duty days are around 30 mins longer. Would that be a good compromise? Downroute reports at -90mins which means fewer trips down to nightstops?
