It appears that BA has just loaded its flight cancellations for June. I was originally booked on a codeshare (AA flight number, BA metal) that is now longer operating. It's not available for booking via BA or AA. When I go into "Manage My Booking" on BA.com, it doesn't show the flight (only an intra-Europe segment that is still operating). However, in AA.com, it's still showing the flight as existing when I look at my reservation details. Does AA typically take a while to load these codeshare changes? Or can I call now to cancel for a refund?
