At 7.54 am on the day of travel whilst driving to London Heathrow I received an email advising my flight had been cancelled. I was offered an alternative flight with AA with downgrade to economy, which I had no alternative but to accept as I must travel today. I was flying to LA to see a family member who is end of life. I called the BA provided telephone number several times was offered no constructive assistance whatsoever. Wrong email address, total waste of time and It was a pointless call. I have been a BA frequent flyer for decades and have been a loyal customer. I now find I am travelling 14hours in Economy without even the possibility of a refund let alone an upgrade. This is completely unacceptable. What has happened to this company? I have had better treatment from Ryanair.
