I had an update ref physical cards/welcome pack. I got this response...

We're truly sorry for the delay(s) you are experiencing in receiving your membership card and luggage tag(s). With the change from Executive Club to The British Airways Club taking place on 1 April 2025, production of items for the new Club has taken longer than anticipated. The latest information available is that we aim to have this resolved by the end of the summer. If you have any further questions please contact British Airways.
