Looking for some advice please, recently had a 3:04 delay, put in a claim but BA have turned it down. They admit that 2 hours 20 is their fault due to a technical problem with the aircraft operating the inbound sector but the remaining 44 minutes delay was due to offloading a sick passenger, spouse and baggage on the instructions of the Captain from our return flight to the UK. According to them I have no basis for a claim, is this correct? Thanks.
