I recently had to cancel some BA flights, they had been bopoked on-line and were cancelled on-line. Due to the reason for cancelling I'm able to claim on my travel insurance but the insurers are insisting on a cancellation invoice showing the amount forfeited.
As far as I'm aware BA don't issue cancellation invoices, the email from BA confirming the cancellation shows the ticket numbers but not the amount lost. I've sent the insurers a copy of the email together with a copy of my CC statement showing the credit from BA (for the taxes etc) which includes the ticket numbers, dates of flights and routing but apparently this isn't sufficient for them and they will only accept a 'cancellation invoice'.
Any ideas how I might be able to get BA to confirm the amount lost in the hope that the insurers will accept this?
