Fantaman - Just wondering, who at BA or LHR does this job? Is there a dedicated team who deal with this sort of problem, ie, re-tasking aircraft, calling out the duty crews etc?
BA782/783 was upgraded from A320 to A321 to provide extra capacity for the offloaded pax from downgraded BA780/781 to B757... Not ideal for 780/781 pax, but everyone got home at the end of the day..
Crew did a usual professional clean up / recovery of BA662...(heard on VHF)
Pax loads was the major feature of the day (being a sunday afternoon), hence ARN downgrade!...
