Booked LHR/DFW/PDX/SEA/LHR in the sale in F on Thursday. Yesterday AS cancelled the PDX/SEA flight. Called You First. Apparently BA have lost the codeshare on the flight can only offer me a flight at 8am with a 10 hour layover. Refused to book me on AA to LAX or SFO. This doesnt sit well with me considering previously there has been no issues rebooking on different flights. Had to cancel and get a refund. Am begining to lose patience with BA rapidly. Thoughts?
