With reference to Aer Lingus flights being full or well subscribed ex BHD. They well be on peak services but plenty of empty seats On the overall London schedule.
I suspect there may be reasons for returning 319 to LGW ex bhd, e.g. Numbers soft enough and pressure of fare, hence 319 lower cost. May be to do with hiring less seasonal staf. equally, moving the 0645 departure time 0740, makes the schedule less attractive to the business man. I suspect reduced numbers expected. BE have made good go of bhd LCY etc.
What is the return date of the 319', does anybody know? I sense that a fleet without 319's has significance for the BHD base...
