Thanks @canucklad for the info. Maybe it should have been posted on the front page of ba.com on the ticker.
I agree mkcol74 the My Flights app is brilliant – It has easy to find information about the fare buckets and also the aircraft changes. At the time of booking if I have picked specific aircraft etc for a particular trip its a invaluable tool for changes.
As an update to the pricing issue I had earlier this has now been corrected and the prices have been updated to reflect the pricing I was tracking. Seems like there were still quite a few gremlins this morning.
Quite a few people with 2-4-1 bookings are seeing mixed arrangements in the Domestic sectors following the thread on HFP.
