Sorry to be a pedant WHBM but while I understand and agree with what you say the example routing of the nurse is in fact one which could be done via LGW since Royal Air Maroc serve it from CMN/RAK and BA fly to Glasgow!
While it seems quite certain that the mainline/national carriers (except maybe the MEB3 and a few other exceptions like Aer Lingus) prefer Heathrow I'm curious as to how Norwegian will grow at LGW, especially when they start getting their 789's. I've read rumours of the two 788's being upgraded to 789's when they start to arrive plus there has been mentions of them considering OAK and BKK and also that FLL has lagged behind the other routes in terms of loads/yield. Does anyone on here have more of an insight into what DY/DU's plans are for LGW?
