The staff on the flight were very nice and helpful but the food was horrible and uneditable, and there was little leg room in economy. The flight was from Heathrow to Vancouver last week which I travelled on. It was delayed for around 2 hours due to a medical emergency of a passenger on board which made me miss my connecting flight. BA refused to let me travel on their next flight as I had booked the onward flight with a different airline unless I paid them for the fare.I recognize it was not BA's fault of this medical emergency but it was definitely not mine either as I had given myself lots of time to get the connecting flight from Vancouver to Kelowna BC. I was on the trip to bring my 30 year old son's ashes back to Canada who died 3 weeks earlier suddenly but the BC ground staff in Vancouver couldn't care less how much stress I was in. I had to slept on the floor all night for hours despite I has assisted need which I had ordered in advance and got. I used to travel often with BA a number of years ago from the UK to Australia the service and food then were excellent. BA has went badly downhill although I recognize BA has at least at the moment, a good safety record which of course is very important.
