I booked this trip in September and yesterday I had a phone call to inform me that because BA had changed their flights to Madeira the holiday was being put back two days from 18th to 20th October 2017.
This is not a problem and I said I was happy with the change. I have received (by email) an amended invoice and find that the price I am being charged has increased by £50. I was under the impression that the price was fixed once a trip was booked, and I would be interested to know why I am being asked to pay more.
My booking reference is A******.
