In all of this thread, the thing that upset me most was the fact that a young woman and her disabled mother were apparently crying without a hotel room stuck in LGW. Probably they had no idea what EU261 or duty of care means. Not everyone is an FT'er or an armchair lawyer.
If I was there and had the means, I would have booked them a 200 GBP hotel room myself, booked them a cab, charged BA for all that, and give a call to DailyMail and add yet more bad publicity to BA.
