British Airways has been fined US$1.1 million for failing to refund flights after they were cancelled during Covid.
The British Airways website apparently instructed passengers to call via phone to discuss refund options but it is almost impossible to reach anyone by phone at British Airways "Customer Service" as I have been personally aware since 2007.
Other misleading advice on the British Airways website led passengers to inadvertently apply for vouchers instead of a refund.
