Its Dec 2023 and yet the very same issue with exact same symptoms exist. What a pathetic state of affairs by BA. Due to this, am losing an option to get a few quids back through the tracking sites like TopCashback. Additionally, i doubt whether the 10 quid paid for holding the booking will ever be reimbursed back, as the payment has to now happen via callcenter and not the link to complete the booking. BA is down the drains.
